16S rRNA (guanine¹⁴⁰⁵-N⁷)-methyltransferase (, ''methyltransferase Sgm'', ''m7G1405 Mtase'', ''Sgm Mtase'', ''Sgm'', ''sisomicin-gentamicin methyltransferase'', ''sisomicin-gentamicin methylase'', ''GrmA'', ''RmtB'', ''RmtC'', ''ArmA'') is an enzyme with systematic name ''S-adenosyl-L-methionine:16S rRNA (guanine¹⁴⁰⁵-N⁷)-methyltransferase''. This enzyme catalyses the following chemical reaction : S-adenosyl-L-methionine + guanine¹⁴⁰⁵ in

16S rRNA 16S rRNA may refer to: * 16S ribosomal RNA 16 S ribosomal RNA (or 16 S rRNA) is the RNA component of the 30S subunit of a prokaryotic ribosome ( SSU rRNA). It binds to the Shine-Dalgarno sequence and provides most of the SSU structure. The g ...
