ENZYME entry: EC 1.14.19.77

Accepted Name
Plasmanylethanolamine desaturase.
Alternative Name(s)
2-acyl-1-alkyl-sn-glycero-3-phosphoethanolamine desaturase.
Alkylacylglycerophosphoethanolamine desaturase.
Reaction catalysed
A plasmanylethanolamine + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> a plasmenylethanolamine + 2 ferricytochrome b5 + 2 H(2)O
Cofactor(s)
Mg(2+).
Comment(s)
  • The enzyme catalyzes the introduction of a double bond at position 1 of the alkyl group attached by an ether bond at the sn-1 position of plasmanylethanolamine, generating a vinyl ether-containing plasmenylethanolamine.
  • The enzyme is found in animals and some bacteria, but not in plants, fungi, or most aerobic bacteria.
  • Formerly EC 1.14.99.19.
