Gene
DES3
Protein
Fatty acid desaturase DES3
Organism
Sorghum bicolor
Length
389 amino acids
Function
Delta(15) fatty acid desaturase capable of converting hexadecadienoic acid into hexadecatrienoic acid (16:3(9Z,12Z,15Z)) (PubMed:17178719). The double bond introduced occurred between carbons 15 and 16 resulting in a terminal double bond aliphatic chain (PubMed:17178719). Can also convert linoleic acid (18:2(9Z,12Z)) into alpha-linolenic acid (18:3(9Z,12Z,15Z)) (PubMed:17178719). Involved in the biosynthesis of the aliphatic side chain of sorgoleone, a phytotoxic secondary metabolite playing a direct role in allelopathic interactions (PubMed:15361534, PubMed:17178719).
Similarity
Belongs to the fatty acid desaturase type 1 family.
