Protein

3-oxoacyl-[acyl-carrier-protein] synthase I, chloroplastic

Gene

KAS12

Organism
Hordeum vulgare (Barley)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Specific for elongation from C-10 to unsaturated C-16 and C-18 fatty acids.

Catalytic activityi

Acyl-[acyl-carrier-protein] + malonyl-[acyl-carrier-protein] = 3-oxoacyl-[acyl-carrier-protein] + CO2 + [acyl-carrier-protein].
