1.14.19.25 | a dihomo-gamma-linolenoyl-[glycerolipid] + 2 ferrocytochrome b5 + O2 + 2 H+ |
(8Z,11Z,14Z)-icosa-8,11,14-trienoyl-[glycerolipid] i.e. dihomo-linolenoyl-[glycerolipid]. Yeast transformant is grown in complete medium containing 0.1% of exogenous fatty acids and then the total fatty acid composition is analyzed by GLC. The enzyme accepts electrons from the microsomal cytochrome b5 or cytochrome b5 motif of another desaturases |
