Protein
Stearoyl-[acyl-carrier-protein] 9-desaturase 2, chloroplastic
Organism
Arabidopsis thaliana
Function
Converts stearoyl-ACP to oleoyl-ACP by introduction of a cis double bond between carbons 9 and 10 of the acyl chain (By similarity). Exhibits delta-9 palmitoyl-[acyl-carrier-protein] desaturase (PAD) activity. Involved in omega-7 monounsaturated fatty acid biosynthesis, especially in the endosperm oil (PubMed:27681170).
Similarity
Belongs to the fatty acid desaturase type 2 family.
