GidB
PFAM accession number:PF02527
Interpro abstract (IPR003682):

This entry represents a rRNA small subunit methyltransferase G. 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. Specifically methylates the N7 position of a guanosine in 16S rRNA [ (PUBMED:12001236) (PUBMED:17238915) (PUBMED:17573471) ].
