ID   1.14.19.77
DE   plasmanylethanolamine desaturase.
AN   2-acyl-1-alkyl-sn-glycero-3-phosphoethanolamine desaturase.
AN   alkylacylglycerophosphoethanolamine desaturase.
CA   1-(1,2-saturated alkyl)-2-acyl-sn-glycero-3-phosphoethanolamine +
CA   2 Fe(II)-[cytochrome b5] + 2 H(+) + O2 = 1-O-(1Z-alkenyl)-2-acyl-
CA   sn-glycero-3-phosphoethanolamine + 2 Fe(III)-[cytochrome b5] + 2 H2O.
CC   -!- The enzyme catalyzes the introduction of a double bond at position 1
CC       of the alkyl group attached by an ether bond at the sn-1 position of
CC       plasmanylethanolamine, generating a vinyl ether-containing
CC       plasmenylethanolamine.
CC   -!- The enzyme is found in animals and some bacteria, but not in plants,
CC       fungi, or most aerobic bacteria.
CC   -!- Formerly EC 1.14.99.19.
