IntEnz Enzyme Nomenclature


Accepted name:
aldehyde oxygenase (deformylating)
Other names:
aldehyde decarbonylase
octadecanal decarbonylase
octadecanal alkane-lyase
Systematic name:
a long-chain aldehyde alkane-lyase




Contains a diiron center. Involved in the biosynthesis of alkanes. The enzyme from the cyanobacterium Nostoc punctiforme PCC 73102 is only active in vitro in the presence of ferredoxin, ferredoxin reductase and NADPH, and produces mostly C15 to C17 alkanes [2]. The enzyme from pea (Pisum sativum) produces alkanes of chain length C18 to C32 and is inhibited by metal-chelating agents [1]. The substrate for this enzyme is formed by EC, acyl-[acyl-carrier protein] reductase.
