Accepted name: 2-enoate reductase

Reaction: butanoate + NAD+ = but-2-enoate + NADH + H+

Other name(s): enoate reductase

Systematic name: butanoate:NAD+ Δ2-oxidoreductase

Comments: An iron-sulfur-flavoprotein (FAD). Acts (in the reverse direction) on a wide range of alkyl and aryl α,β-unsaturated carboxylate ions; but-2-enoate was the best substrate tested.
