Ketonization of proline residues in the peptide chains of actinomycins by a 4‐Oxoproline synthase
S Semsary, I Crnovčić, R Driller, J Vater, B Loll… - …, 2018 - Wiley Online Library
X-type actinomycins (Acms) contain 4-hydroxyproline (Acm X0) or 4-oxoproline (Acm X2) in
their ß-pentapeptide lactone rings whereas their α-ring contains proline. We demonstrate
that these Acms are formed through asymmetric condensation of Acm half molecules (Acm …
