Accepted name: 2,4-dienoyl-CoA reductase [(3E)-enoyl-CoA-producing]
Reaction: (1) a (3E)-3-enoyl-CoA + NADP+ = a (2E,4E)-2,4-dienoyl-CoA + NADPH + H+
(2) a (3E)-3-enoyl-CoA + NADP+ = a (2E,4Z)-2,4-dienoyl-CoA + NADPH + H+
Other name(s): SPS19 (gene name); DECR1 (gene name); DECR2 (gene name); Δ24-dienoyl-CoA reductase (ambiguous)
Systematic name: (3E)-3-enoyl-CoA:NADP+ 4-oxidoreductase
Comments: This enzyme, characterized from eukaryotic organisms, catalyses the reduction of either (2E,4E)-2,4-dienoyl-CoA or (2E,4Z)-2,4-dienoyl-CoA to (3E)-3-enoyl-CoA. The best substrates for the enzyme from bovine liver have a chain-length of 8 or 10 carbons. Mammals possess both mitochondrial and peroxisomal variants of this enzyme. cf. EC, 2,4-dienoyl-CoA reductase [(2E)-enoyl-CoA-producing].
