EC 1.3.1.44     
Accepted name: trans-2-enoyl-CoA reductase (NAD+)
Reaction: acyl-CoA + NAD+ = trans-didehydroacyl-CoA + NADH + H+
Other name(s): trans-2-enoyl-CoA reductase (NAD)
Systematic name: acyl-CoA:NAD+ trans-2-oxidoreductase
Comments: The enzyme from Euglena gracilis acts on crotonoyl-CoA and, more slowly, on trans-hex-2-enoyl-CoA and trans-oct-2-enoyl-CoA.
