Product Name sn-1 linoleoyl-lipid 6-desaturase
Example Structure Example Structure of sn-1 linoleoyl-lipid 6-desaturase EC#: 1.14.19.46
Synonyms DELTA6 desaturase, DELTA6-acyl-lipid desaturase, DELTA6-desaturase, desD
EC Number 1.14.19.46
CAS Registry Number
Comments The enzyme, characterized from cyanobacteria, introduces a cis double bond at carbon 6 of linoleoyl groups (18:2) attached to the sn-1 position of glycerolipids. The enzyme is a front-end desaturase, introducing the new double bond between a pre-existing double bond and the carboxyl-end of the fatty acid. It is nonspecific with respect to the polar head group of the glycerolipid.
