ID 1.3.1.84 DE acrylyl-CoA reductase (NADPH). CA NADP(+) + propanoyl-CoA = acryloyl-CoA + H(+) + NADPH. CC -!- Catalyzes a step in the 3-hydroxypropanoate/4-hydroxybutyrate cycle, CC an autotrophic CO2 fixation pathway found in some thermoacidophilic CC archaea. CC -!- The reaction is catalyzed in the opposite direction to that shown. CC -!- The enzyme from Sulfolobus tokodaii does not act on either NADH or CC crotonyl-CoA. CC -!- Different from EC 1.3.1.8, which acts only on enoyl-CoA derivatives CC of carbon chain length 4 to 16.
