SYSTEMATIC NAME
IUBMB Comments
1-acyl-2-palmitoyl-[glycerolipid],ferredoxin:oxygen oxidoreductase (7,8-cis-dehydrogenating)
The enzyme introduces a cis double bond at carbon 7 of a palmitoyl group attached to the sn-2 position of glycerolipids. The enzyme from the plant Arabidopsis thaliana is specific for palmitate in monogalactosyldiacylglycerol.
