Protein	Synonyms	Taxonomy
S-adenosyl-L-methionine-dependent uroporphyrinogen III methyltransferase, chloroplastic	Urophorphyrin III methylase; EC 2.1.1.107; Urophorphyrin methylase 1; AtUPM1	Arabidopsis thaliana (thale cress)

Compound	Description
hydronium ion
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
