2.1.1.179 | S-adenosyl-L-methionine + guanine1405 in 16S rRNA |
methylation at guanine1405 mediates cellular resistance by blocking aminoglycoside binding by ribosomes |

2.1.1.179 | S-adenosyl-L-methionine + guanine1405 in 16S rRNA |
the ArmA methylation reaction is specific for the 30S ribosomal subunit. Neither 16S rRNA alone nor the 70S ribosome is a substrate for this reaction under experimental conditions, implicating ribosomal proteins in substrate recognition |
