physiological function
rmtC is responsible for resistance of strain ARS68 and its transformant to various aminoglycoside antibiotics
physiological function
methylation of C1405, involved in the binding of aminoglycosides to 16S rRNA, can lead to loss of affinity and to resistance of the host. Resistance conferred by RmtF cannot be transferred to Escherichia coli via transfer of plasmid pIP849

LITERATURE
purified Sgm is complexed with 5 mM of the cofactors S-adenosylmethionine/S-adenosylhomocysteine. Crystallization trials are carried out at room temperature by hanging-drop vapor-diffusion method, structure of Sgm in complex with cofactors S-adenosylmethionine and S-adenosylhomocysteine is determined at 2.0 A and 2.1 A resolution, respectively
in complex with S-adenosylhomocysteine. An N-terminal domain surface within RmtC, comprising basic residues from both the N1 and N2 subdomains, directly contributes to 30S-binding affinity. Additional residues lining a contiguous adjacent surface on the C-terminal domain are critical for 16S rRNA modification but do not directly contribute to the binding affinity

gene rmtF encoded on a non-self-transferable plasmid pIP849, cotranscribed with the upstream aac(6')-Ib gene, DNA and amino acid sequence determination, analysis, and comparisons, overview. Genetic structure and phylogenetic tree
introduction of a recombinant version of the Sgm methyltransferase gene from Micromonospora zionensis into an Escherichia coli strain that has a full complement of housekeeping methyltransferases. Analyses of the 16S rRNA shows that the m5C1407-specific housekeeping methyltransferase RsmF (YebU) is outcompeted by Sgm as the resistance methyltransferase gains access to its own m7G1405 target on the 30S ribosomal subunit. A single amino acid change in Sgm, which lowers the level of conferred resistance, reduces the ability of Sgm to interfere with RsmF methylation on the 30S subunit
sgm is cloned into a yeast expression vector to test whether the prokaryotic methylases can modify the 18S rRNA A-site and thus confer resistance to the aminoglycoside antibiotic G-418. Sgm does not provide resistant phenotypes to yeast cells. Despite all similarities in the antibiotic binding site, methylation by Sgm does not occur in yeast, suggesting that the recognition site for these methylases could be different in 30S and 40S subunits
