Cloning and biochemical characterization of a class A beta-lactamase from Prevotella intermedia.

ABSTRACT: The gene encoding a beta-lactamase of Prevotella intermedia was cloned and sequenced. This gene, called cfxA2, shared 98% identity with cfxA, the structural gene of a beta-lactamase previously described in Bacteroides vulgatus. The deduced protein sequence had a K272E substitution. CfxA2 had the characteristics of class A, group 2e beta-lactamases.

Biochemical-genetic characterization of the chromosomally encoded extended-spectrum class A beta-lactamase from Rahnella aquatilis.

Project description:From whole-cell DNA of a clinical isolate of the enterobacterial species Rahnella aquatilis, a beta-lactamase gene was cloned that encoded a chromosomally encoded Ambler class A enzyme, RAHN-1. RAHN-1, with a pI of 7.2, shares 76, 73, and 71% amino acid identity with the extended-spectrum beta-lactamase of chromosomal origin from Serratia fonticola and with the plasmid-mediated beta-lactamases CTX-M-2 and CTX-M-1, respectively. The hydrolysis spectrum of the clavulanic acid-inhibited RAHN-1 was expanded to cephalosporins such as cefuroxime, cefotaxime, and ceftriaxone, but not to ceftazidime. Its expression was not inducible.

Molecular and biochemical characterization of a novel class A beta-lactamase (HER-1) from Escherichia hermannii.

Project description:Escherichia hermannii showed a low level of resistance to amoxicillin and ticarcillin, reversed by clavulanate, and a moderate susceptibility to piperacillin but was susceptible to all cephalosporins. A bla gene was cloned and encoded a typical class A beta-lactamase (HER-1, pI 7.5), which shares 45, 44, 41, and 40% amino acid identity with other beta-lactamases, AER-1 from Aeromonas hydrophila, MAL-1/Cko-1 from Citrobacter koseri, and TEM-1 and LEN-1, respectively. No ampR gene was detected. Only penicillins were efficiently hydrolyzed, and no hydrolysis was observed for cefuroxime and broad-spectrum cephalosporins. Sequencing of the bla gene in 12 other strains showed 98 to 100% identity with bla(HER-1).

Molecular and biochemical characterization of the natural chromosome-encoded class A beta-lactamase from Pseudomonas luteola.

Project description:Pseudomonas luteola (formerly classified as CDC group Ve-1 and named Chryseomonas luteola) is an unusual pathogen implicated in rare but serious infections in humans. A novel beta-lactamase gene, bla(LUT-1), was cloned from the whole-cell DNA of the P. luteola clinical isolate LAM, which had a weak narrow-spectrum beta-lactam-resistant phenotype, and expressed in Escherichia coli. This gene encoded LUT-1, a 296-amino-acid Ambler class A beta-lactamase with a pI of 6 and a theoretical molecular mass of 28.9 kDa. The catalytic efficiency of this enzyme was higher for cephalothin, cefuroxime, and cefotaxime than for penicillins. It was found to be 49% to 59% identical to other Ambler class A beta-lactamases from Burkholderia sp. (PenA to PenL), Ralstonia eutropha (REUT), Citrobacter sedlakii (SED-1), Serratia fonticola (FONA and SFC-1), Klebsiella sp. (KPC and OXY), and CTX-M extended-spectrum beta-lactamases. No gene homologous to the regulatory ampR genes of class A beta-lactamases was found in the vicinity of the bla(LUT-1) gene. The entire bla(LUT-1) coding region was amplified by PCR and sequenced in five other genetically unrelated P. luteola strains (including the P. luteola type strain). A new variant of bla(LUT-1) was found for each strain. These genes (named bla(LUT-2) to bla(LUT-6)) had nucleotide sequences 98.1 to 99.5% identical to that of bla(LUT-1) and differing from this gene by two to four nonsynonymous single nucleotide polymorphisms. The bla(LUT) gene was located on a 700- to 800-kb chromosomal I-CeuI fragment, the precise size of this fragment depending on the P. luteola strain.

Genetic and biochemical characterization of TRU-1, the endogenous class C beta-lactamase from Aeromonas enteropelogenes.

Project description:Aeromonas enteropelogenes (formerly A. tructi) was described to be an ampicillin-susceptible and cephalothin-resistant Aeromonas species, which suggests the production of a cephalosporinase. Strain ATCC 49803 was susceptible to amoxicillin, cefotaxime, and imipenem but resistant to cefazolin (MICs of 2, 0.032, 0.125, and >256 microg/ml, respectively) and produced an inducible beta-lactamase. Cefotaxime-resistant mutants (MIC, 32 microg/ml) that showed constitutive beta-lactamase production could be selected in vitro. The gene coding for the cephalosporinase of A. enteropelogenes ATCC 49803 was cloned, and its biochemical properties were investigated. Escherichia coli transformants showing resistance to various beta-lactams carried a 3.5-kb plasmid insert whose sequence revealed a 1,146-bp open reading frame (ORF) encoding a class C beta-lactamase, named TRU-1, showing the highest identity scores with A. punctata CAV-1 (75%), A. salmonicida AmpC (75%), and A. hydrophila CepH (71%). The bla(TRU-1) locus includes open reading frames (ORFs) showing significant homology with genes found in the genomes of other Aeromonas species, although it exhibits a different organization, as reflected by the presence of additional ORFs located downstream of the beta-lactamase gene in the A. hydrophila and A. salmonicida genomes. Specific PCR assays were negative for cphA-like and bla(OXA-12)-like genes in three A. enteropelogenes ATCC strains. Purified TRU-1 showed a broad substrate profile, efficiently hydrolyzing benzylpenicillin, cephalothin, cefoxitin, and, although with significantly lower turnover rates, oxyiminocephalosporins. Cephaloridine and cefepime were poorly recognized by the enzyme, as reflected by the high K(m) values observed with these substrates. Thus far, A. enteropelogenes represents the only known example of an Aeromonas species that produces only one beta-lactamase belonging to molecular class C.

Cloning and characterization of a chromosomal class C beta-lactamase and its regulatory gene in Laribacter hongkongensis.

Project description:Laribacter hongkongensis, a newly discovered bacterium recently shown to be associated with community-acquired gastroenteritis, is generally resistant to most beta-lactams except the carbapenems. We describe the cloning and characterization of a novel chromosomal class C beta-lactamase and its regulatory gene in L. hongkongensis. Two genes, ampC and ampR, were cloned by inserting restriction fragments of genomic DNA from L. hongkongensis strain HLHK5 into pBK-CMV to give the recombinant plasmid pBK-LHK-5. The ampR and ampC genes and their promoters were divergently oriented, with the ampR gene immediately upstream of the ampC gene and an intercistronic Lys-R motif, typical of inducible ampC-ampR regulatory systems. The deduced amino acid sequence of the cloned AmpC beta-lactamase (pI 8.1) contained consensus motifs characteristic of class C beta-lactamases but had identities no greater than 46% to known class C beta-lactamases. The kinetic properties of this AmpC were also compatible with those of a class C beta-lactamase. PCR of 20 clinical isolates of L. hongkongensis, including HLHK5, showed the presence of both ampC and ampR genes in all isolates. Southern hybridization suggested that the ampC gene of HLHK5 was chromosomally encoded. Subcloning experiments showed that the expression of the ampC gene of HLHK5 was regulated by its ampR gene, which acts as a repressor. The beta-lactamase characterized from strain HLHK5 was named LHK-5 (gene, bla(LHK-5)) and represents the first example of AmpC beta-lactamase in the beta subdivision of proteobacteria.

Molecular and biochemical characterization of Ambler class A extended-spectrum beta-lactamase CGA-1 from Chryseobacterium gleum.

Project description:Antibiotic susceptibility testing by disk diffusion of a Chryseobacterium gleum isolate, strain CIP 103039, showed a typical synergy image between clavulanic acid and expanded-spectrum cephalosporins. Shotgun cloning gave a recombinant plasmid in Escherichia coli that produced a beta-lactamase, CGA-1, with a pI value of 8.9 that conferred resistance to most penicillins (except ureidopenicillins) and narrow-spectrum cephalosporins and an intermediate susceptibility to expanded-spectrum cephalosporins and aztreonam. The CGA-1 amino acid sequence shared only 60% amino acid identity with CME-1 and CME-2 from Chryseobacterium meningosepticum, the most closely related beta-lactamases. CGA-1 was very likely chromosome encoded. It is a novel member of the PER subgroup of Ambler class A beta-lactamases (Bush functional group 2be).

Molecular and biochemical characterization of OXA-45, an extended-spectrum class 2d' beta-lactamase in Pseudomonas aeruginosa.

Project description:As part of the CANCER Antimicrobial Surveillance Program in North America, a clinical strain of Pseudomonas aeruginosa, strain 07-406, isolated in Texas was found to be resistant to all antimicrobials except polymyxin B. Genetic analysis of this isolate identified two unique extended-spectrum beta-lactamase genes. One, bla(VIM-7), encoded a metallo-beta-lactamase (unpublished data), and the other, bla(OXA-45), described here, encoded a class D extended-spectrum beta-lactamase. bla(OXA-45) was isolated on a Sau3A1 genomic fragment of 1.8 kb and encodes a protein of 264 amino acids with the highest identities to OXA-18 (65.9%), OXA-9 (42.8%), OXA-22 (40.2%), OXA-12 (38.6%), and OXA-29 (35.2%) but weak identities with other class D beta-lactamases. bla(OXA-45) was found to be harbored on a 24-kb plasmid in a region that displays high identities with a section of the 43-kb genomic island of Salmonella enterica serovar Typhimurium DT104. Biochemically OXA-45 is most similar to OXA-18 in its substrate profile and inhibition by clavulanic acid and is a member of the 2d' class of beta-lactamases.

Genetic and biochemical characterization of OXA-63, a new class D beta-lactamase from Brachyspira pilosicoli BM4442.

Project description:Brachyspira pilosicoli BM4442, isolated from the feces of a patient with diarrhea at the Hospital Saint-Michel in Paris, was resistant to oxacillin (MIC > 256 microg/ml) but remained susceptible to cephalosporins and to the combination of amoxicillin and clavulanic acid. Cloning and sequencing of the corresponding resistance determinant revealed a coding sequence of 807 bp encoding a new class D beta-lactamase named OXA-63. The bla OXA-63 gene was chromosomally located and not part of a transposon or of an integron. OXA-63 shared 54% identity with FUS-1 (OXA-85), an oxacillinase from Fusobacterium nucleatum subsp. polymorphum, and 25 to 44% identity with other class D beta-lactamases (DBLs) and contained all the conserved structural motifs of DBLs. Escherichia coli carrying the bla OXA-63 gene exhibited resistance to benzylpenicillin and amoxicillin but remained susceptible to amoxicillin in combination with clavulanic acid. Mature OXA-63 consisted of a 31.5-kDa polypeptide and appeared to be dimeric. Kinetic analysis revealed that OXA-63 exhibited a narrow substrate profile, hydrolyzing oxacillin, benzylpenicillin, and ampicillin with catalytic efficiencies of 980, 250, and 150 mM(-1) s(-1), respectively. The enzyme did not apparently interact with oxyimino-cephalosporins, imipenem, or aztreonam. Unlike FUS-1 and other DBLs, OXA-63 was strongly inhibited by clavulanic acid (50% inhibitory concentration [IC50] of 2 microM) and tazobactam (IC50 of 0.16 microM) and exhibited low susceptibility to NaCl (IC50 of >2 M). OXA-63 is the first DBL described for the anaerobic spirochete B. pilosicoli.

Molecular and biochemical characterization of the chromosome-encoded class A beta-lactamase BCL-1 from Bacillus clausii.

Project description:A chromosomal beta-lactamase gene from Bacillus clausii NR, which is used as a probiotic, was cloned and expressed in Escherichia coli. It encodes a clavulanic acid-susceptible Ambler class A beta-lactamase, BCL-1, with a pI of 5.5 and a molecular mass of ca. 32 kDa. It shares 91% and 62% amino acid identity with the chromosomally encoded PenP penicillinases from B. clausii KSM-K16 and Bacillus licheniformis, respectively. The hydrolytic profile of this beta-lactamase includes penicillins, narrow-spectrum cephalosporins, and cefpirome. This chromosome-encoded enzyme was inducible in B. clausii, and its gene is likely related to upstream-located regulatory genes that share significant identity with those reported to be upstream of the penicillinase gene of B. licheniformis. The bla(BCL-1) gene was located next to the known chromosomal aadD2 gene and the erm34 gene, which encode resistance to aminoglycosides and macrolides, respectively. Similar genes were found in a collection of B. clausii reference strains.
