Accepted name: 4-amino-L-phenylalanyl-[CmlP-peptidyl-carrier-protein] 3-hydroxylase
Reaction: 4-amino-L-phenylalanyl-[CmlP-peptidyl-carrier-protein] + reduced acceptor + O2 = 2-(4-aminophenyl)-L-seryl-[CmlP-peptidyl-carrier-protein] + acceptor + H2O
Other name(s): cmlA (gene name)
Systematic name: 4-amino-L-phenylalanyl-[CmlP-peptidyl-carrier-protein],acceptor:oxygen 3-oxidoreductase
Comments: The enzyme, characterized from the bacterium Streptomyces venezuelae, participates in the biosynthesis of the antibiotic chloramphenicol. It carries an oxygen-bridged dinuclear iron cluster. The native electron donor remains unknown, and the enzyme was assayed in vitro using sodium dithionite. The enzyme only acts on its substrate when it is loaded onto the peptidyl-carrier domain of the CmlP non-ribosomal peptide synthase.
