Abstact

Nonribosomal peptide synthetases produce many important peptide natural products and are centred around carrier proteins (CPs) that deliver intermediates to various catalytic domains. We show that the replacement of CP substrate thioesters by stabilised ester analogues leads to active condensation domain complexes, whereas amide stabilisation generates non-functional complexes.
