Protein

Enoyl-[acyl-carrier-protein] reductase [NADPH] FabL

Gene

fabL

Organism
Bacillus subtilis (strain 168)

Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). It confers resistance to triclosan.1 Publication

Catalytic activityi

An acyl-[acyl-carrier protein] + NADP+ = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADPH.1 Publication

Enzyme regulationi

Inhibited by triclosan.1 Publication

Kineticsi

  1. KM=16 µM for NADPH1 Publication
