NAD(P)-dependent oxidoreductase
This domain is found in fungi, plants, archaea and bacteria. (from Pfam)
SAM-dependent methyltransferase
This family uses S-AdoMet in the methylation of diverse substrates. This family includes a related group of bacterial proteins of unknown function, including Swiss:P45528. This family includes the methylase Dipthine synthase. (from Pfam)
siroheme synthase
siroheme synthase catalyzes all three steps of siroheme biosynthesis, including methylation, oxidation, and iron insertion into the tetrapyrrole uroporphyrinogen III (Uro-III)
uroporphyrinogen-III C-methyltransferase
This HMM represents enzymes, or enzyme domains, with uroporphyrin-III C-methyltransferase activity. This enzyme catalyzes the first step committed to the biosynthesis of either siroheme or cobalamin (vitamin B12) rather than protoheme (heme). Cobalamin contains cobalt while siroheme contains iron. Siroheme is a cofactor for nitrite and sulfite reductases and therefore plays a role in cysteine biosynthesis; many members of this family are CysG, siroheme synthase, with an additional N-terminal domain and with additional oxidation and iron insertion activities.
