Protein

3-oxoacyl-[acyl-carrier-protein] reductase FabG

Gene

fabG

Organism
Salmonella typhi
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the NADPH-dependent reduction of beta-ketoacyl-ACP substrates to beta-hydroxyacyl-ACP products, the first reductive step in the elongation cycle of fatty acid biosynthesis.By similarity

Miscellaneous

Calcium ions stabilize the structure, and may inhibit FabG activity by obstructing access to the active site.By similarity

Catalytic activityi

(3R)-3-hydroxyacyl-[acyl-carrier-protein] + NADP+ = 3-oxoacyl-[acyl-carrier-protein] + NADPH.
