Protein
Delta(5) fatty acid desaturase fat-4
Organism
Caenorhabditis elegans
Function
Catalyzes the desaturation of dihomo-gamma-linoleic acid (DHGLA) (20:3n-6) to generate arachidonic acid (20:4n-6). Also acts on a number of other substrates, including fatty acids that do not contain a double bond at the 8 position.
Similarity
Belongs to the fatty acid desaturase type 1 family.
