UniProtKB - Q8KA28 (FABB_BUCAP)
Protein
3-oxoacyl-[acyl-carrier-protein] synthase 1
Gene
fabB
Organism
Buchnera aphidicola subsp. Schizaphis graminum (strain Sg)
Status
Functioni
Involved in the type II fatty acid elongation cycle. Catalyzes the elongation of a wide range of acyl-ACP by the addition of two carbons from malonyl-ACP to an acyl acceptor. Can also use unsaturated fatty acids. Catalyzes a key reaction in unsaturated fatty acid (UFA) synthesis, the elongation of the cis-3-decenoyl-ACP produced by FabA.
By similarityCatalytic activityi
- EC:2.3.1.41By similarityThis reaction proceeds in the forwardBy similarity direction.
- (3Z)-decenoyl-[ACP] + H+ + malonyl-[ACP] = 3-oxo-(5Z)-dodecenoyl-[ACP] + CO2 + holo-[ACP]By similarityThis reaction proceeds in the forwardBy similarity direction.
: fatty acid biosynthesis Pathwayi
