Mechanism of acylation catalyzed by BAHD acyltransferases. Acyl donors are activated upon esterification of their carboxylic group (COOH) with coenzyme A (CoA). BAHD acyltransferases using 4-hydroxycinnamoyl-CoAs (R = 4-hydroxystyrene) and benzoyl-CoAs (R = benzene) as donors were used for this study. R’ = BAHD acceptor
