IntEnz Enzyme Nomenclature
EC 2.3.3.20

Names

Accepted name:
acyl-CoA:acyl-CoA alkyltransferase
Other name:
oleA (gene name)
Systematic name:
acyl-CoA:acyl-CoA alkyltransferase [(2R)-2-alkyl-3-oxoalkanoate-forming]

Reaction

Comments:

The enzyme, found in certain bacterial species, catalyses a head-to-head non-decarboxylative Claisen condensation of two acyl-CoA molecules, resulting in formation of a 2-alkyl-3-oxoalkanoic acid. It is part of a pathway for the production of olefins.
