Reaction: (1) 1-(1-alkenyl)-sn-glycero-3-phosphocholine + H2O = an aldehyde + sn-glycero-3-phosphocholine
(2) 1-(1-alkenyl)-sn-glycero-3-phosphoethanolamine + H2O = an aldehyde + sn-glycero-3-phosphoethanolamine
Other name(s): alkenylglycerophosphocholine hydrolase; alkenylglycerophosphoethanolamine hydrolase; 1-(1-alkenyl)-sn-glycero-3-phosphocholine aldehydohydrolase
Systematic name: lysoplasmalogen aldehydohydrolase
Comments: Lysoplasmalogenase is specific for the sn-2-deacylated (lyso) form of plasmalogen and catalyses hydrolytic cleavage of the vinyl ether bond, releasing a fatty aldehyde and sn-glycero-3-phosphocholine or sn-glycero-3-phosphoethanolamine.
