rRNA small subunit methyltransferase G; This is a family of bacterial glucose inhibited division proteins these are probably involved in the regulation of cell devision. GidB has been shown to be a methyltransferase G specific to the rRNA small subunit. Previously identified as a glucose-inhibited division protein B that appears to be present and in a single copy in all complete eubacterial genomes so far sequenced. GidB specifically methylates the N7 position of a guanosine in 16S rRNA.

16S rRNA (guanine(527)-N(7))-methyltransferase RsmG; RsmG was previously called GidB (glucose-inhibited division protein B). It is present and a single copy in nearly all complete eubacterial genomes. It is missing only from some obligate intracellular species of various lineages (Chlamydiae, Ehrlichia, Wolbachia, Anaplasma, Buchnera, etc.). RsmG shows a methytransferase fold in its the crystal structure, and acts as a 7-methylguanosine (m(7)G) methyltransferase, apparently specific to 16S rRNA.

68-162 2.92e-08

S-adenosylmethionine-dependent methyltransferases (SAM or AdoMet-MTase), class I; AdoMet-MTases are enzymes that use S-adenosyl-L-methionine (SAM or AdoMet) as a substrate for methyltransfer, creating the product S-adenosyl-L-homocysteine (AdoHcy). There are at least five structurally distinct families of AdoMet-MTases, class I being the largest and most diverse. Within this class enzymes can be classified by different substrate specificities (small molecules, lipids, nucleic acids, etc.) and different target atoms for methylation (nitrogen, oxygen, carbon, sulfur, etc.).
