PubMed Abstract:
Through a number of strategies nonribosomal peptide assembly lines give rise to a metabolic diversity not possible by ribosomal synthesis. One distinction within nonribosomal assembly is that products are elaborated on an enzyme-tethered substrate, and their release is enzyme catalysed. Reductive release by NAD(P)H-dependent catalysts is one observed nonribosomal termination and release strategy. Here we probed the selectivity of a terminal reductase domain by using a full-length heterologously expressed nonribosomal peptide synthetase for the dipeptide aureusimine and were able to generate 17 new analogues. Further, we generated an X-ray structure of aureusimine terminal reductase to gain insight into the structural details associated with this enzymatic domain.
