16S rRNA (adenine1408-N1)-methyltransferase (EC 2.1.1.180, kanamycin-apramycin resistance methylase, 16S rRNA:m1A1408 methyltransferase, KamB, NpmA, 16S rRNA m1A1408 methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:16S rRNA (adenine1408-N1)-methyltransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-methionine + adenine1408 in 16S rRNA [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + N1-methyladenine1408 in 16S rRNA
The enzyme provides a panaminoglycoside resistance through interference with the binding of aminoglycosides.
