| NADH | |
| iron | A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN. |
| siroheme | the heme prosthetic group of the hemoprotein of E coli NADPH-sulfite reductase; reduces sulfite to sulfide or nitrite to ammonia; structure |
| nad | A coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). (Dorland, 27th ed) |
| s-adenosylmethionine | Physiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It possesses anti-inflammatory activity and has been used in treatment of chronic liver disease. (From Merck, 11th ed) |
| Ethacridine | A topically applied anti-infective agent. |
| sirohydrochlorin | chromophore of desulfoviridin; structure |
| 15,23-dihydrosirohydrochlorin | structure given in first source |
