S-AdoMet-dependent tetrapyrrole methylases; This superfamily uses S-AdoMet (S-adenosyl-L-methionine or SAM) in the methylation of diverse substrates. Most members catalyze various methylation steps in cobalamin (vitamin B12) biosynthesis. There are two distinct cobalamin biosynthetic pathways in bacteria. The aerobic pathway requires oxygen, and cobalt is inserted late in the pathway; the anaerobic pathway does not require oxygen, and cobalt insertion is the first committed step towards cobalamin synthesis. The enzymes involved in the aerobic pathway are prefixed Cob and those of the anaerobic pathway Cbi. Most of the enzymes are shared by both pathways and a few enzymes are pathway-specific. Diphthine synthase and ribosomal RNA small subunit methyltransferase I (RsmI) are two superfamily members that are not involved in cobalamin biosynthesis. Diphthine synthase participates in the posttranslational modification of a specific histidine residue in elongation factor 2 (EF-2) of eukaryotes and archaea to diphthamide. RsmI catalyzes the 2-O-methylation of the ribose of cytidine 1402 (C1402) in 16S rRNA. Other superfamily members not involved in cobalamin biosynthesis include the N-terminal tetrapyrrole methylase domain of Bacillus subtilis YabN whose specific function is unknown, and Omphalotus olearius omphalotin methyltransferase which catalyzes the automethylation of its own C-terminus; this C terminus is subsequently released and macrocyclized to give Omphalotin A, a potent nematicide.

siroheme synthase, N-terminal domain; This model represents a subfamily of CysG N-terminal region-related sequences. All sequences in the seed alignment for this model are N-terminal regions of known or predicted siroheme synthases. The C-terminal region of each is uroporphyrin-III C-methyltransferase (EC 2.1.1.107), which catalyzes the first step committed to the biosynthesis of either siroheme or cobalamin (vitamin B12) rather than protoheme (heme). The region represented by this model completes the process of oxidation and iron insertion to yield siroheme. Siroheme is a cofactor for nitrite and sulfite reductases, so siroheme synthase is CysG of cysteine biosynthesis in some organisms.

Uroporphyrin-III C-methyltransferase (also known as S-Adenosyl-L-methionine:uroporphyrinogen III methyltransferase, SUMT); SUMT is an enzyme of the cobalamin and siroheme biosynthetic pathway. It catalyzes the first of three steps leading to the formation of siroheme from uroporphyrinogen III; it transfers two methyl groups from S-adenosyl-L-methionine to the C-2 and C-7 atoms of uroporphyrinogen III to yield precorrin-2 via the intermediate formation of precorrin-1. Precorrin-2 is also a precursor for the biosynthesis of vitamin B12, coenzyme F430, siroheme and heme d1. This family includes proteins in which the SUMT domain is fused to other functional domains, such as to a uroporphyrinogen-III synthase domain to form bifunctional uroporphyrinogen-III methylase/uroporphyrinogen-III synthase, or to a dual function dehydrogenase-chelatase domain, as in the case of the multifunctional S-adenosyl-L-methionine (SAM)-dependent bismethyltransferase/dehydrogenase/ferrochelatase CysG, which catalyzes all three steps that transform uroporphyrinogen III into siroheme.

Sirohaem synthase dimerization region; Bacterial sulfur metabolism depends on the iron-containing porphinoid sirohaem. CysG, S-adenosyl-L-methionine (SAM)-dependent bis-methyltransferase, dehydrogenase and ferrochelatase, synthesizes sirohaem from uroporphyrinogen III via reactions which encompass two branchpoint intermediates in tetrapyrrole biosynthesis, diverting flux first from protoporphyrin IX biosynthesis and then from cobalamin (vitamin B12) biosynthesis. CysG is a dimer of two structurally similar protomers held together asymmetrically through a number of salt-bridges across complementary residues in the CysG_dimerizer region to produce a series of active sites, accounting for CysG's multifunctionality, catalysing four diverse reactions: two SAM-dependent methylations, NAD+-dependent tetrapyrrole dehydrogenation and metal chelation. The CysG_dimerizer region holding the two protomers together is of 74 residues. Pssm-ID: 431269 [Multi-domain] Cd Length: 56 Bit Score: 49.86 E-value: 2.17e-08
