Crystallization and preliminary X-ray analysis of the subclass B3 metallo-?-lactamase SMB-1 that confers carbapenem resistance.

ABSTRACT: The carbapenem-hydrolyzing subclass B3 metallo-?-lactamase SMB-1 was expressed in Escherichia coli and purified. Diffraction data were collected from two types of SMB-1 crystals that were obtained under different conditions. One crystal (SMB-1a) belonged to the trigonal space group P3(1) with unit-cell parameters a = b = 67.83, c = 48.67 Å, while the other crystal (SMB-1b) also belonged to space group P3(1) but with unit-cell parameters a = b = 67.25, c = 46.83 Å. Both crystals contained one molecule per asymmetric unit. Initial phases were determined by molecular replacement; further refinement and model building are in progress.

Structural Insights into Recognition of Hydrolyzed Carbapenems and Inhibitors by Subclass B3 Metallo-?-Lactamase SMB-1.

Project description:Metallo-?-lactamases (MBLs) confer resistance to carbapenems, and their increasing global prevalence is a growing clinical concern. To elucidate the mechanisms by which these enzymes recognize and hydrolyze carbapenems, we solved 1.4 to 1.6 Å crystal structures of SMB-1 (Serratia metallo-?-lactamase 1), a subclass B3 MBL, bound to hydrolyzed carbapenems (doripenem, meropenem, and imipenem). In these structures, SMB-1 interacts mainly with the carbapenem core structure via elements in the active site, including a zinc ion (Zn-2), Q157[113] (where the position in the SMB-1 sequence is in brackets after the BBL number), S221[175], and T223[177]. There is less contact with the carbapenem R2 side chains, strongly indicating that SMB-1 primarily recognizes the carbapenem core structure. This is the first report describing how a subclass B3 MBL recognizes carbapenems. We also solved the crystal structure of SMB-1 in complex with the approved drugs captopril, an inhibitor of the angiotensin-converting enzyme, and 2-mercaptoethanesulfonate, a chemoprotectant. These drugs are inhibitors of SMB-1 with Ki values of 8.9 and 184 ?M, respectively. Like carbapenems, these inhibitors interact with Q157[113] and T223[177] and their thiol groups coordinate the zinc ions in the active site. Taken together, the data indicate that Q157[113], S221[175], T223[177], and the two zinc ions in the active site are key targets in the design of SMB-1 inhibitors with enhanced affinity. The structural data provide a solid foundation for the development of effective inhibitors that would overcome the carbapenem resistance of MBL-producing multidrug-resistant microbes.

Structural insights into the subclass B3 metallo-?-lactamase SMB-1 and the mode of inhibition by the common metallo-?-lactamase inhibitor mercaptoacetate.

Project description:A novel subclass B3 metallo-?-lactamase (MBL), SMB-1, recently identified from a Serratia marcescens clinical isolate, showed a higher hydrolytic activity against a wide range of ?-lactams than did the other subclass B3 MBLs, i.e., BJP-1 and FEZ-1, from environmental bacteria. To identify the mechanism underlying the differences in substrate specificity among the subclass B3 MBLs, we determined the structure of SMB-1, using 1.6-Å diffraction data. Consequently, we found that SMB-1 reserves a space in the active site to accommodate ?-lactam, even with a bulky R1 side chain, due to a loss of amino acid residues corresponding to F31 and L226 of BJP-1, which protrude into the active site to prevent ?-lactam from binding. The protein also possesses a unique amino acid residue, Q157, which probably plays a role in recognition of ?-lactams via the hydrogen bond interaction, which is missing in BJP-1 and FEZ-1, whose K(m) values for ?-lactams are particularly high. In addition, we determined the mercaptoacetate (MCR)-complexed SMB-1 structure and revealed the mode of its inhibition by MCR: the thiolate group bridges to two zinc ions (Zn1 and Zn2). One of the carboxylate oxygen atoms of MCR makes contact with Zn2 and Ser221, and the other makes contact with T223 and a water molecule. Our results demonstrate the possibility that MCR could be a potent inhibitor for subclass B3 MBLs and that the screening technique using MCR as an inhibitor would be effective for detecting subclass B3 MBL producers.

SMB-1, a novel subclass B3 metallo-beta-lactamase, associated with ISCR1 and a class 1 integron, from a carbapenem-resistant Serratia marcescens clinical isolate.

Project description:A carbapenem-resistant Serratia marcescens strain, 10mdr148, was identified in a Japanese hospital in 2010. The carbapenem resistance of this strain was attributed to the production of a novel metallo-?-lactamase (MBL), named SMB-1 (Serratia metallo-?-lactamase). SMB-1 possessed a zinc binding motif, H(Q)XHXDH (residues 116 to 121), H196, and H263 and was categorized as a member of subclass B3 MBL. SMB-1 has 75% amino acid identity with the most closely related MBL, AMO1, of uncultured bacterium, recently identified through the metagenomic analysis of apple orchard soil. The introduction of bla(SMB-1) into Escherichia coli conferred resistance to a variety of ?-lactam antibiotics, penicillins, cephalosporins, and carbapenems, but not aztreonam, a resistance pattern consistent with those of other MBLs. SMB-1 demonstrated high k(cat) values of >500 s(-1) for carbapenems, resulting in the highest hydrolyzing efficiency (k(cat)/K(m)) among the agents tested. The hydrolyzing activity of SMB-1 was well inhibited by chelating agents. The bla(SMB-1) gene was located on the chromosome of S. marcescens strain 10mdr148 and at the 3' end of the ISCR1 element in complex with a typical class 1 integron carrying aac(6')-Ib and catB3 gene cassettes. Downstream of bla(SMB-1), the second copy of the 3'conserved segment and ISCR1 were found. To our knowledge, this is the first subclass B3 MBL gene associated with an ISCR1 element identified in an Enterobacteriaceae clinical isolate. A variety of antibiotic resistance genes embedded with ISCR1 have been widely spread among Enterobacteriaceae clinical isolates, thus the further dissemination of bla(SMB-1) mediated by ISCR1 transposition activity may become a future concern.

4-Amino-2-Sulfanylbenzoic Acid as a Potent Subclass B3 Metallo-?-Lactamase-Specific Inhibitor Applicable for Distinguishing Metallo-?-Lactamase Subclasses.

Project description:The number of cases of infection with carbapenem-resistant Enterobacteriaceae (CRE) has been increasing and has become a major clinical and public health concern. Production of metallo-?-lactamases (MBLs) is one of the principal carbapenem resistance mechanisms in CRE. Therefore, developing MBL inhibitors is a promising strategy to overcome the problems of carbapenem resistance conferred by MBLs. To date, the development and evaluation of MBL inhibitors have focused on subclass B1 MBLs but not on B3 MBLs. In the present study, we searched for B3 MBL (specifically, SMB-1) inhibitors and found thiosalicylic acid (TSA) to be a potent inhibitor of B3 SMB-1 MBL (50% inhibitory concentration [IC50], 0.95??M). TSA inhibited the purified SMB-1 to a considerable degree but was not active against Escherichia coli cells producing SMB-1, as the meropenem (MEM) MIC for the SMB-1 producer was only slightly reduced with TSA. We then introduced a primary amine to TSA and synthesized 4-amino-2-sulfanylbenzoic acid (ASB), which substantially reduced the MEM MICs for SMB-1 producers. X-ray crystallographic analyses revealed that ASB binds to the two zinc ions, Ser221, and Thr223 at the active site of SMB-1. These are ubiquitously conserved residues across clinically relevant B3 MBLs. ASB also significantly inhibited other B3 MBLs, including AIM-1, LMB-1, and L1. Therefore, the characterization of ASB provides a starting point for the development of optimum B3 MBL inhibitors.

Biochemical Characterization of CPS-1, a Subclass B3 Metallo-?-Lactamase from a Chryseobacterium piscium Soil Isolate.

Project description:CPS-1 is a subclass B3 metallo-?-lactamase from a Chryseobacterium piscium isolate collected from soil, showing 68% amino acid identity to the GOB-1 enzyme. CPS-1 was overproduced in Escherichia coli Rosetta (DE3), purified by chromatography, and biochemically characterized. This enzyme exhibits a broad-spectrum substrate profile, including penicillins, cephalosporins, and carbapenems, which overall resembles those of L1, GOB-1, and acquired subclass B3 enzymes AIM-1 and SMB-1.

Structural and Biochemical Characterization of Rm3, a Subclass B3 Metallo-?-Lactamase Identified from a Functional Metagenomic Study.

Project description:?-Lactamase production increasingly threatens the effectiveness of ?-lactams, which remain a mainstay of antimicrobial chemotherapy. New activities emerge through both mutation of previously known ?-lactamases and mobilization from environmental reservoirs. The spread of metallo-?-lactamases (MBLs) represents a particular challenge because of their typically broad-spectrum activities encompassing carbapenems, in addition to other ?-lactam classes. Increasingly, genomic and metagenomic studies have revealed the distribution of putative MBLs in the environment, but in most cases their activity against clinically relevant ?-lactams and, hence, the extent to which they can be considered a resistance reservoir remain uncharacterized. Here we characterize the product of one such gene, blaRm3, identified through functional metagenomic sampling of an environment with high levels of biocide exposure. blaRm3 encodes a subclass B3 MBL that, when expressed in a recombinant Escherichia coli strain, is exported to the bacterial periplasm and hydrolyzes clinically used penicillins, cephalosporins, and carbapenems with an efficiency limited by high Km values. An Rm3 crystal structure reveals the MBL superfamily ??/?? fold, which more closely resembles that in mobilized B3 MBLs (AIM-1 and SMB-1) than other chromosomal enzymes (L1 or FEZ-1). A binuclear zinc site sits in a deep channel that is in part defined by a relatively extended N terminus. Structural comparisons suggest that the steric constraints imposed by the N terminus may limit its affinity for ?-lactams. Sequence comparisons identify Rm3-like MBLs in numerous other environmental samples and species. Our data suggest that Rm3-like enzymes represent a distinct group of B3 MBLs with a wide distribution and can be considered an environmental reservoir of determinants of ?-lactam resistance.

Mutational Effects on Carbapenem Hydrolysis of YEM-1, a New Subclass B2 Metallo-?-Lactamase from Yersinia mollaretii.

Project description:Analysis of the genome sequence of Yersinia mollaretii ATCC 43969 identified the bla YEM gene, encoding YEM-1, a putative subclass B2 metallo-?-lactamase. The objectives of our work were to produce and purify YEM-1 and to complete its kinetic characterization. YEM-1 displayed the narrowest substrate range among known subclass B2 metallo-?-lactamases, since it can hydrolyze imipenem, but not other carbapenems, such as biapenem, meropenem, doripenem, and ertapenem, with high catalytic efficiency. A possible explanation of this activity profile is the presence of tyrosine at residue 67 (loop L1), threonine at residue 156 (loop L2), and serine at residue 236 (loop L3). We showed that replacement of Y67 broadened the activity profile of the enzyme for all carbapenems but still resulted in poor activity toward the other ?-lactam classes.

The Legionella (Fluoribacter) gormanii metallo-beta-lactamase: a new member of the highly divergent lineage of molecular-subclass B3 beta-lactamases.

Project description:A metallo-beta-lactamase determinant was cloned from a genomic library of Legionella (Fluoribacter) gormanii ATCC 33297(T) constructed in the plasmid vector pACYC184 and transformed into Escherichia coli DH5alpha, by screening for clones showing a reduced susceptibility to imipenem. The product of the cloned determinant, named FEZ-1, contains a 30-kDa polypeptide and exhibits an isoelectric pH of 7.6. Sequencing revealed that FEZ-1 is a molecular-class B beta-lactamase which shares the closest structural similarity (29.7% of identical residues) with the L1 enzyme of Stenotrophomonas maltophilia, being a new member of the highly divergent subclass B3 lineage. All the residues that in L1 are known to be directly or indirectly involved in coordination of the zinc ions were found to be conserved also in FEZ-1, suggesting that the geometry of zinc coordination in the active site of the latter enzyme is identical to that of L1. Unlike L1, however, FEZ-1 appeared to be monomeric in gel permeation chromatography experiments and exhibited a distinctive substrate specificity with a marked preference for cephalosporins and meropenem. The properties of FEZ-1 overall resembled those of a beta-lactamase previously purified from the same strain of L. gormanii (T. Fujii, K. Sato, K. Miyata, M. Inoue, and S. Mitsuhashi, Antimicrob. Agents Chemother. 29:925-926, 1986) and are as yet unique among class B enzymes, reinforcing the notion that considerable functional heterogeneity can be encountered among members of this class. A system for overexpression of the bla(FEZ-1) gene in E. coli, based on the T7 phage promoter, was also developed.

Crystallization and preliminary diffraction studies of GIM-1, a class B carbapenem-hydrolyzing ?-lactamase.

Project description:GIM-1 is a member of the class B carbapenemases (metallo-?-lactamases; MBLs) and has a wide spectrum of activity against carbapenems, penicillins and extended-spectrum cephalosporins, but not aztreonam. GIM-1 presents an enormous challenge to infection control, particularly in the eradication of Gram-negative pathogens including Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii and nonfermenters. There are presently few or no drugs in late-stage development for these pathogens and GIM-1 is a potential target for the development of antimicrobial agents against pathogens producing MBLs. In this study, GIM-1 was cloned, overexpressed and crystallized. The GIM-1 crystals diffracted to 1.4?Å resolution and belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 38.5, b = 67.6, c = 72.8?Å. One molecule is present in the asymmetric unit, with a corresponding V(M) of 1.69?Å(3)?Da(-1) and a solvent content of 27.1%.

Postgenomic scan of metallo-beta-lactamase homologues in rhizobacteria: identification and characterization of BJP-1, a subclass B3 ortholog from Bradyrhizobium japonicum.

Project description:The diffusion of metallo-beta-lactamases (MBLs) among clinically important human pathogens represents a therapeutic issue of increasing importance. However, the origin of these resistance determinants is largely unknown, although an important number of proteins belonging to the MBL superfamily have been identified in microbial genomes. In this work, we analyzed the distribution and function of genes encoding MBL-like proteins in the class Rhizobiales. Among 12 released complete genomes of members of the class Rhizobiales, a total of 57 open reading frames (ORFs) were found to have the MBL conserved motif and identity scores with MBLs ranging from 8 to 40%. On the basis of the best identity scores with known MBLs, four ORFs were cloned into Escherichia coli for heterologous expression. Among their products, one (blr6230) encoded by the Bradyrhizobium japonicum USDA110 genome, named BJP-1, hydrolyzed beta-lactams when expressed in E. coli. BJP-1 enzyme is most closely related to the CAU-1 enzyme from Caulobacter vibrioides (40% amino acid sequence identity), a member of subclass B3 MBLs. A kinetic analysis revealed that BJP-1 efficiently hydrolyzed most beta-lactam substrates, except aztreonam, ticarcillin, and temocillin, with the highest catalytic efficiency measured with meropenem. Compared to other MBLs, BJP-1 was less sensitive to inactivation by chelating agents.
