IUBMB Enzyme Nomenclature


Accepted name: cis-3-alkyl-4-alkyloxetan-2-one decarboxylase

Reaction: a cis-3-alkyl-4-alkyloxetan-2-one = a cis-alkene + CO2

Other name(s): oleB (gene name)

Systematic name: cis-3-alkyl-4-alkyloxetan-2-one carboxy-lyase (cis-alkene-forming)

Comments: The enzyme, found in certain bacterial species, catalyses the last step in a pathway for the production of olefins.
