Protein

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

Gene
fabG, PA2967
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / PAO1 / 1C / PRS 101 / LMG 12228)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

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.

Catalytic activityi

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