Accepted name: alkylglycerol monooxygenase
Reaction: 1-O-alkyl-sn-glycerol + tetrahydrobiopterin + O2 = 1-O-(1-hydroxyalkyl)-sn-glycerol + dihydrobiopterin + H2O
Other name(s): glyceryl-ether monooxygenase; glyceryl-ether cleaving enzyme; 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 non-heme iron [7], reduced glutathione and phospholipids for full activity. The product spontaneously breaks down to form a fatty aldehyde and glycerol.
