IUBMB Enzyme Nomenclature


Accepted name: L-allo-isoleucyltransferase

Reaction: L-allo-isoleucyl-S-[CmaA peptidyl-carrier protein] + holo-[CmaD peptidyl-carrier protein] = L-allo-isoleucyl-S-[CmaD peptidyl-carrier protein] + holo-[CmaA peptidyl-carrier protein]

Glossary: L-allo-isoleucine = (2S,3R)-2-amino-3-methylpentanoic acid

Other name(s): CmaE

Systematic name: L-allo-isoleucyl-S-[CmaA peptidyl-carrier protein]:holo-[CmaD peptidyl-carrier protein] L-allo-isoleucyltransferase

Comments: The enzyme, characterized from the bacterium Pseudomonas syringae, is involved in the biosynthesis of the toxin coronatine.
