Abstract

Covering: up to July 2018 Non-ribosomal peptide synthetase (NRPS) machineries are complex, multi-domain proteins that are responsible for the biosynthesis of many important, peptide-derived compounds. By decoupling peptide synthesis from the ribosome, NRPS assembly lines are able to access a significant pool of amino acid monomers for peptide synthesis. This is combined with a modular protein architecture that allows for great variation in stereochemistry, peptide length, cyclisation state and further modifications. The architecture of NRPS assembly lines relies upon a repetitive set of catalytic domains, which are organised into modules responsible for amino acid incorporation. Central to NRPS-mediated biosynthesis is the carrier protein (CP) domain, to which all intermediates following initial monomer activation are bound during peptide synthesis up until the final handover to the thioesterase domain that cleaves the mature peptide from the NRPS. This mechanism makes understanding the protein-protein interactions that occur between different NRPS domains during peptide biosynthesis of crucial importance to understanding overall NRPS function. This endeavour is also highly challenging due to the inherent flexibility and dynamics of NRPS systems. In this review, we present the current state of understanding of the protein-protein interactions that govern NRPS-mediated biosynthesis, with a focus on insights gained from structural studies relating to CP domain interactions within these impressive peptide assembly lines.
