FunFam 2533: Ribosomal RNA small subunit methyltransferase A

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
16S rRNA (adenine(1518)-N(6)/adenine(1519)-N(6))-dimethyltransferase. [EC: 2.1.1.182]
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.
