GO
GO:0016491 Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. GO:0010181 Binding to flavin mono nucleotide. Flavin mono nucleotide (FMN) is the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes. GO:0008670 Catalysis of the reactions: a 4,5-saturated-(2E)-enoyl-CoA + NADP+ = a (2E,4E)-dienoyl-CoA + H+ + NADPH, and a (2E,4Z)-dienoyl-CoA + H+ + NADPH = a 4,5-saturated-(2E)-enoyl-CoA + NADP+. GO:0051536 Binding to an iron-sulfur cluster, a combination of iron and sulfur atoms. GO:0046872 Binding to a metal ion. GO:0033543 A fatty acid beta-oxidation pathway by which fatty acids having cis-double bonds on even-numbered carbons are degraded. In this pathway, the intermediate 2,4-dienoyl-CoA is converted to trans-2-enoyl-CoA by 2,4-dienoyl-CoA reductase and delta3-delta2-enoyl-CoA isomerase; trans-2-enoyl-CoA returns to the core beta-oxidation pathway for further degradation. Fatty acid beta-oxidation begins with the addition of coenzyme A to a fatty acid, and ends when only two or three carbons remain (as acetyl-CoA or propionyl-CoA respectively).
