Protein-protein interactions in "cis-AT" polyketide synthases.

ABSTRACT: Covering: up to the end of 2018 Polyketides are a valuable source of bioactive and clinically important molecules. The biosynthesis of these chemically complex molecules has led to the discovery of equally complex polyketide synthase (PKS) pathways. Crystallography has yielded snapshots of individual catalytic domains, di-domains, and multi-domains from a variety of PKS megasynthases, and cryo-EM studies have provided initial views of a PKS module in a series of defined biochemical states. Here, we review the structural and biochemical results that shed light on the protein-protein interactions critical to catalysis by PKS systems with an embedded acyltransferase. Interactions include those that occur both within and between PKS modules, as well as with accessory enzymes.

Structural analysis of protein-protein interactions in type I polyketide synthases.

Project description:Polyketide synthases (PKSs) are responsible for synthesizing a myriad of natural products with agricultural, medicinal relevance. The PKSs consist of multiple functional domains of which each can catalyze a specified chemical reaction leading to the synthesis of polyketides. Biochemical studies showed that protein-substrate and protein-protein interactions play crucial roles in these complex regio-/stereo-selective biochemical processes. Recent developments on X-ray crystallography and protein NMR techniques have allowed us to understand the biosynthetic mechanism of these enzymes from their structures. These structural studies have facilitated the elucidation of the sequence-function relationship of PKSs and will ultimately contribute to the prediction of product structure. This review will focus on the current knowledge of type I PKS structures and the protein-protein interactions in this system.

Type II fatty acid and polyketide synthases: deciphering protein-protein and protein-substrate interactions.

Project description:Covering: up to April 5, 2018 Metabolites from type II fatty acid synthase (FAS) and polyketide synthase (PKS) pathways differ broadly in their identities and functional roles. The former are considered primary metabolites that are linear hydrocarbon acids, while the latter are complex aromatic or polyunsaturated secondary metabolites. Though the study of bacterial FAS has benefitted from decades of biochemical and structural investigations, type II PKSs have remained less understood. Here we review the recent approaches to understanding the protein-protein and protein-substrate interactions in these pathways, with an emphasis on recent chemical biology and structural applications. New approaches to the study of FAS have highlighted the critical role of the acyl carrier protein (ACP) with regard to how it stabilizes intermediates through sequestration and selectively delivers cargo to successive enzymes within these iterative pathways, utilizing protein-protein interactions to guide and organize enzymatic timing and specificity. Recent tools that have shown promise in FAS elucidation should find new approaches to studying type II PKS systems in the coming years.

Protein-Protein Interactions, Not Substrate Recognition, Dominate the Turnover of Chimeric Assembly Line Polyketide Synthases.

Project description:The potential for recombining intact polyketide synthase (PKS) modules has been extensively explored. Both enzyme-substrate and protein-protein interactions influence chimeric PKS activity, but their relative contributions are unclear. We now address this issue by studying a library of 11 bimodular and 8 trimodular chimeric PKSs harboring modules from the erythromycin, rifamycin, and rapamycin synthases. Although many chimeras yielded detectable products, nearly all had specific activities below 10% of the reference natural PKSs. Analysis of selected bimodular chimeras, each with the same upstream module, revealed that turnover correlated with the efficiency of intermodular chain translocation. Mutation of the acyl carrier protein (ACP) domain of the upstream module in one chimera at a residue predicted to influence ketosynthase-ACP recognition led to improved turnover. In contrast, replacement of the ketoreductase domain of the upstream module by a paralog that produced the enantiomeric ACP-bound diketide caused no changes in processing rates for each of six heterologous downstream modules compared with those of the native diketide. Taken together, these results demonstrate that protein-protein interactions play a larger role than enzyme-substrate recognition in the evolution or design of catalytically efficient chimeric PKSs.

Comparative analysis of the substrate specificity of trans- versus cis-acyltransferases of assembly line polyketide synthases.

Project description:Due to their pivotal role in extender unit selection during polyketide biosynthesis, acyltransferase (AT) domains are important engineering targets. A subset of assembly line polyketide synthases (PKSs) are serviced by discrete, trans-acting ATs. Theoretically, these trans-ATs can complement an inactivated cis-AT, promoting introduction of a noncognate extender unit. This approach requires a better understanding of the substrate specificity and catalytic mechanism of naturally occurring trans-ATs. We kinetically analyzed trans-ATs from the disorazole and kirromycin synthases and compared them to a representative cis-AT from the 6-deoxyerythronolide B synthase (DEBS). During transacylation, the disorazole AT favored malonyl-CoA over methylmalonyl-CoA by >40000-fold, whereas the kirromycin AT favored ethylmalonyl-CoA over methylmalonyl-CoA by 20-fold. Conversely, the disorazole AT had broader specificity than its kirromycin counterpart for acyl carrier protein (ACP) substrates. The presence of the ACP had little effect on the specificity (k(cat)/K(M)) of the cis-AT domain for carboxyacyl-CoA substrates but had a marked influence on the corresponding specificity parameters for the trans-ATs, suggesting that these enzymes do not act strictly by a canonical ping-pong mechanism. To investigate the relevance of the kinetic analysis of isolated ATs in the context of intact PKSs, we complemented an in vitro AT-null DEBS assembly line with either trans-AT. Whereas the disorazole AT efficiently complemented the mutant PKS at substoichiometric protein ratios, the kirromycin AT was considerably less effective. Our findings suggest that knowledge of both carboxyacyl-CoA and ACP specificity is critical to the choice of a trans-AT in combination with a mutant PKS to generate novel polyketides.

Iterative polyketide biosynthesis by modular polyketide synthases in bacteria.

Project description:Modular polyketide synthases (type I PKSs) in bacteria are responsible for synthesizing a significant percentage of bioactive natural products. This group of synthases has a characteristic modular organization, and each module within a PKS carries out one cycle of polyketide chain elongation; thus each module is non-iterative in function. It was possible to predict the basic structure of a polyketide product from the module organization of the PKSs, since there generally existed a co-linearity between the number of modules and the number of chain elongations. However, more and more bacterial modular PKSs fail to conform to the canonical rules, and a particularly noteworthy group of non-canonical PKSs is the bacterial iterative type I PKSs. This review covers recent examples of iteratively used modular PKSs in bacteria. These non-canonical PKSs give rise to a large array of natural products with impressive structural diversity. The molecular mechanism behind the iterations is often unclear, presenting a new challenge to the rational engineering of these PKSs with the goal of generating new natural products. Structural elucidation of these synthase complexes and better understanding of potential PKS-PKS interactions as well as PKS-substrate recognition may provide new prospects and inspirations for the discovery and engineering of new bioactive polyketides.

Protein-protein recognition between acyltransferases and acyl carrier proteins in multimodular polyketide synthases.

Project description:Acyltransferase (AT) domains of multimodular polyketide synthases are the primary gatekeepers for stepwise incorporation of building blocks into a growing polyketide chain. Each AT domain has two substrates, an alpha-carboxylated CoA thioester (e.g., malonyl-CoA or methylmalonyl-CoA) and an acyl carrier protein (ACP). Whereas the acyl-CoA specificity of AT domains has been extensively investigated, little is known about their ACP specificity. Guided by recent high-resolution structural insights, we have systematically probed the protein-protein interactions between AT domains, ACP domains, and the linkers that flank AT domains. Representative AT domains of the 6-deoxyerythronolide B synthase (DEBS) have greater than 10-fold specificity for their cognate ACP substrates as compared to other ACP domains from the same synthase. Both of the flanking (N- and C-terminal) linkers of an AT domain contributed to the efficiency and specificity of transacylation. As a frame of reference, the activity and specificity of a stand-alone AT domain from the "AT-less" disorazole synthase (DSZS) were also quantified. The activity (k(cat)/K(M)) of this AT was >250-fold higher than the corresponding values for DEBS AT domains. Although the AT from DSZS discriminated modestly against ACP domains from DEBS, it exhibited >40-fold higher activity in trans in the presence of these heterologous substrates than their natural AT domains. Our results highlight the opportunity for regioselective modification of a polyketide backbone by in trans complementation of inactivated AT domains. They also reinforce the need for more careful consideration of protein-protein interactions in the engineering of these assembly line enzymes.

Evolution of polyketide synthases in bacteria.

Project description:The emergence of resistant strains of human pathogens to current antibiotics, along with the demonstrated ability of polyketides as antimicrobial agents, provides strong motivation for understanding how polyketide antibiotics have evolved and diversified in nature. Insights into how bacterial polyketide synthases (PKSs) acquire new metabolic capabilities can guide future laboratory efforts in generating the next generation of polyketide antibiotics. Here, we examine phylogenetic and structural evidence to glean answers to two general questions regarding PKS evolution. How did the exceptionally diverse chemistry of present-day PKSs evolve? And what are the take-home messages for the biosynthetic engineer?

Employing 25-Residue Docking Motifs from Modular Polyketide Synthases as Orthogonal Protein Connectors.

Project description:The proteins of trans-acyltransferase modular polyketide synthases (PKSs) self-organize into assembly lines, enabling the multienzyme biosynthesis of complex organic molecules. Docking domains comprised of ?25 residues at the C- and N-termini of these polypeptides (CDDs and NDDs) help drive this association through the formation of four-helix bundles. Molecular connectors like these are desired in synthetic contexts, such as artificial biocatalytic systems and biomaterials, to orthogonally join proteins. Here, the ability of six CDD/NDD pairs to link non-PKS proteins is examined using green fluorescent protein (GFP) variants. As observed through size-exclusion chromatography and Förster resonance energy transfer (FRET), matched but not mismatched pairs of Venus+CDD and NDD+mTurquoise2 fusion proteins associate with low micromolar affinities.

Structure and mechanism of assembly line polyketide synthases.

Project description:Assembly line polyketide synthases (PKSs) are remarkable biosynthetic machines with considerable potential for structure-based engineering. Several types of protein-protein interactions, both within and between PKS modules, play important roles in the catalytic cycle of a multimodular PKS. Additionally, vectorial biosynthesis is enabled by the energetic coupling of polyketide chain elongation to the channeling of intermediates between successive modules. A combination of high-resolution analysis of smaller PKS components and lower resolution characterization of intact modules and bimodules has yielded insights into the structure and organization of a prototypical assembly line PKS. This review discusses our understanding of key structure-function relationships in this family of megasynthases, along with a recap of key unanswered questions in the field.

SBSPKS: structure based sequence analysis of polyketide synthases.

Project description:Polyketide synthases (PKSs) catalyze biosynthesis of a diverse family of pharmaceutically important secondary metabolites. Bioinformatics analysis of sequence and structural features of PKS proteins plays a crucial role in discovery of new natural products by genome mining, as well as in design of novel secondary metabolites by biosynthetic engineering. The availability of the crystal structures of various PKS catalytic and docking domains, and mammalian fatty acid synthase module prompted us to develop SBSPKS software which consists of three major components. Model_3D_PKS can be used for modeling, visualization and analysis of 3D structure of individual PKS catalytic domains, dimeric structures for complete PKS modules and prediction of substrate specificity. Dock_Dom_Anal identifies the key interacting residue pairs in inter-subunit interfaces based on alignment of inter-polypeptide linker sequences to the docking domain structure. In case of modular PKS with multiple open reading frames (ORFs), it can predict the cognate order of substrate channeling based on combinatorial evaluation of all possible interface contacts. NRPS-PKS provides user friendly tools for identifying various catalytic domains in the sequence of a Type I PKS protein and comparing them with experimentally characterized PKS/NRPS clusters cataloged in the backend databases of SBSPKS. SBSPKS is available at http://www.nii.ac.in/sbspks.html.
