Polyketide Bioderivatization Using the Promiscuous Acyltransferase KirCII
ACS Synthetic Biology, 6(3), 421–427.
author keywords: antibiotic; kirromycin; polyketide synthase; trans-acyltransferase; engineering click chemistry
MeSH headings : Acyltransferases / metabolism; Anti-Bacterial Agents / metabolism; Bacteria / metabolism; Bacterial Proteins / metabolism; Polyketide Synthases / metabolism; Polyketides / metabolism; Pyridones / metabolism
topics (OpenAlex): Microbial Natural Products and Biosynthesis; Enzyme Production and Characterization; Carbohydrate Chemistry and Synthesis
TL;DR:
This work exploits the promiscuity of KirCII to generate new kirromycins with allyl- and propargyl-side chains in vivo, and the latter were utilized as educts for further modification by "click" chemistry.

Promiscuity of a modular polyketide synthase towards natural and non-natural extender units
Organic & Biomolecular Chemistry, 11(27), 4449.
MeSH headings : Acyl Coenzyme A / chemistry; Acyl Coenzyme A / metabolism; Bacterial Proteins / chemistry; Bacterial Proteins / metabolism; Coenzyme A Ligases / chemistry; Coenzyme A Ligases / metabolism; Polyketide Synthases / chemistry; Polyketide Synthases / metabolism; Protein Structure, Tertiary; Rhizobium / chemistry; Rhizobium / enzymology; Rhizobium / metabolism; Substrate Specificity
topics (OpenAlex): Microbial Natural Products and Biosynthesis; Fungal Biology and Applications; Enzyme Catalysis and Immobilization
TL;DR:
A panel of chemo-enzymatically synthesized acyl-CoA's was used to probe the promiscuity of a polyketide synthase, revealing that the KS is remarkably tolerant to a diverse array of extender units, while the AT likely discriminates betweenextender units that are native to the producing organism.
