IUBMB Enzyme Nomenclature


Accepted name: alkylglycerol monooxygenase

Reaction: 1-alkyl-sn-glycerol + tetrahydrobiopterin + O2 = 1-O-alkyl-sn-glycerol + dihydrobiopterin + H2O

Other name(s): glyceryl-ether monooxygenase; glyceryl-ether cleaving enzyme; alkylglycerol monooxygenase; glyceryl ether oxygenase; glyceryl etherase; O-alkylglycerol monooxygenase

Systematic name: 1-alkyl-sn-glycerol,tetrahydrobiopterin:oxygen oxidoreductase

Comments: The enzyme cleaves alkylglycerols, but does not cleave alkenylglycerols (plasmalogens). Requires reduced glutathione and phospholipids for full activity. The product spontaneously breaks down to form a fatty aldehyde and glycerol.
