EC 4.1.99.5 Details
EC number
4.1.99.5
Accepted name
aldehyde oxygenase (deformylating)
Reaction
a long-chain aldehyde + O2 + 2 NADPH + 2 H+ = an alkane + formate + H2O + 2 NADP+
Other name(s)
decarbonylase, aldehyde decarbonylase, octadecanal decarbonylase, octadecanal alkane-lyase
Systematic name
a long-chain aldehyde alkane-lyase
CAS registry number
94185-90-7
Comment
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 and C17 alkanes [2,3]. 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 1.2.1.80, acyl-[acyl-carrier protein] reductase.
