IUBMB Enzyme Nomenclature


Accepted name: olefin β-lactone synthetase

Reaction: ATP + a (2R,3S)-2-alkyl-3-hydroxyalkanoate = AMP + diphosphate + a cis-3-alkyl-4-alkyloxetan-2-one

Other name(s): oleC (gene name)

Systematic name: (2R,3S)-2-alkyl-3-hydroxyalkanoate ligase (β-lactone,AMP-forming)

Comments: The enzyme, found in certain bacterial species, participates in a pathway for the production of olefins. It forms a β-lactone. The alkyl group at C2 of the substrate ends up as the 3-alkyl group of the product.
