IUBMB Enzyme Nomenclature


Accepted name: (3R)-3-[(carboxylmethyl)amino]fatty acid synthase

Reaction: (3R)-3-[(carboxylmethyl)amino]fatty acid + an [acyl-carrier protein] = a (2E)-unsaturated fatty acyl-[acyl-carrier protein] + glycine + H2O

Other name(s): scoD (gene name); mmaD (gene name)

Systematic name: (3R)-3-[(carboxylmethyl)amino]fatty acid glycine-lyase ((2E)-unsaturated fatty acyl-[acyl-carrier protein]-forming)

Comments: The enzyme, found in some actinobacterial species, participates in the biosynthesis of isonitrile-containing lipopeptides. It catalyses the formation of (3R)-3-[(carboxylmethyl)amino]fatty acid by the addition of glycine and the release of the product from the acyl-carrier protein.
