Bergler, H, Wallner, P, Ebeling, A, Leitinger, B, Fuchsbichler, S, Aschauer, H, Kollenz, G, Högenauer, G and Turnowsky, F (1994) Protein EnvM is the NADH-dependent enoyl-ACP reductase (FabI) of Escherichia coli. J. Biol. Chem. 269:5493-6

Abstract

The EnvM protein was purified from an overproducing Escherichia coli strain. It showed NADH-dependent enoyl-acyl carrier protein (ACP) reductase activity using both crotonyl-ACP and crotonyl-CoA as substrates. The protein bound a radioactive diazaborine derivative in the presence of NAD+ and radioactive NAD+ in the presence of the drug. Based on these data, it is concluded that EnvM is the NADH-dependent enoyl-ACP reductase (EC 1.3.1.9) of E. coli and we propose to rename the corresponding gene fabI.
