Enzyme Information
| 2.1.1.182 |
16S rRNA (adenine(1518)-N(6)/adenine(1519)-N(6))-dimethyltransferase.
based on mapping to UniProt Q1RK29
4 S-adenosyl-L-methionine + adenine(1518)/adenine(1519) in 16S rRNA = 4 S-adenosyl-L-homocysteine + N(6)-dimethyladenine(1518)/N(6)- dimethyladenine(1519) in 16S rRNA.
-!- KsgA introduces the most highly conserved ribosomal RNA modification, the dimethylation of adenine(1518) and adenine(1519) in 16S rRNA. -!- Strains lacking the methylase are resistant to kasugamycin. -!- Formerly EC 2.1.1.48.
