Metabolite Identification
Common NamePrecorrin-2
DescriptionPrecorrin-2 is an intermediate in the siroheme biosynthesis pathway. Siroheme is an iron-containing isobacteriochlorin, a modified tetrapyrrole similar in structure to both heme and chlorophyll. Siroheme is found as a prosthetic group of several enzymes, including sulfite and nitrite reductases, which catalyze the six-electron reductions of sulfite to sulfide and nitrite to ammonia, respectively. Siroheme biosynthesis starts by the same route as other tetrapyrroles, the synthesis of the intermediate uroporphyrinogen-III. [Biocyc PWY-5194]
