uncharacterized subfamily of the tetrapyrrole methylase family similar to Ribosomal RNA small subunit methyltransferase I (RsmI); RsmI, also known as rRNA (cytidine-2'-O-)-methyltransferase, is an S-AdoMet (S-adenosyl-L-methionine or SAM)-dependent methyltransferase responsible for the 2'-O-methylation of cytidine 1402 (C1402) at the P site of bacterial 16S rRNA. Another S-AdoMet-dependent methyltransferase, RsmH (not included in this family), is responsible for N4-methylation at C1402. These methylation reactions may occur at a late step during 30S assembly in the cell. The dimethyl modification is believed to be conserved in bacteria, may play a role in fine-tuning the shape and functions of the P-site to increase the translation fidelity, and has been shown for Staphylococcus aureus, to contribute to virulence in host animals by conferring resistance to oxidative stress. : Pssm-ID: 381176 Cd Length: 229 Bit Score: 393.33 E-value: 1.08e-140

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.
