Escherichia coli K-12 substr. MG1655 Enzyme: trans-2-enoyl-CoA reductase

Subunit composition of trans-2-enoyl-CoA reductase = [subunit of trans-2-enoyl-CoA reductase (NADPH)]2

Summary:
There is no gene yet identified for this enzyme.

Gene-Reaction Schematic: ?


Enzymatic reaction of: trans-2-enoyl-CoA reductase

Synonyms: acyl-CoA:NADP+ trans-2-oxidoreductase

EC Number: 1.3.1.38

a 2,3,4-saturated fatty acyl CoA + NADP+ <=> a trans-2-enoyl-CoA + NADPH + H+

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction of enzyme catalysis.

The reaction is irreversible in the direction shown.

Alternative Substrates [Comment 1]:

Summary:
NADPH-dependent trans-2-enoyl-CoA reductase is distinct from the three other enoyl-CoA reductases in E. coli. The reductase may participate in the chain elongation or degradation of fatty acids. This reaction is similar to the acyl-CoA dehydrogenase reaction, the fadE gene product. There is no gene associated with this enzyme as yet. [Mizugaki82, Nishimaki84]

Inhibitors (Competitive): NADP+ [Nishimaki84, Comment 2] , saturated acyl-CoA [Nishimaki84]

Inhibitors (Unknown Mechanism): p-hydroxymercuribenzoate [Nishimaki84] , N-ethylmaleimide [Nishimaki84] , 5,5'-dithio-bis-2-nitrobenzoate [Nishimaki84]
