Cfr 23S ribosomal RNA methyltransferase [AMR Gene Family]

Accession ARO:3000202
DefinitionCfr genes produce enzymes which catalyze the methylation of the 23S rRNA subunit at position 8 of adenine-2503. Methylation of 23S rRNA at this site confers resistance to some classes of antibiotics, including streptogramins, chloramphenicols, florfenicols, linezolids and clindamycin.
Drug Classoxazolidinone antibiotic, phenicol antibiotic, streptogramin antibiotic, macrolide antibiotic, lincosamide antibiotic
Resistance Mechanismantibiotic target alteration
