Cfr confers a phenotype with resistance to phenicols, lincosamides, oxazolidinones, pleuromutilins, and streptogramin A antibiotics. Methylation of position 8 is the dominant antibiotic resistance determinant, but indigenous modification at position 2 also contributes to low-level resistance |

2.1.1.224 | more |
enzyme Cfr methylates adenosine 2503 of the 23S rRNA in the peptidyltransferase centre (P-site) of the bacterial ribosome. In wild-type Cfr, where Cys338 is methylated, S-adenosyl-L-methionine binding leads to rapid oxidation of the [4Fe-4S] cluster and production of 5'-deoxyadenosine |

Cfr methylates A2503 of 23S rRNA at C8 and C2, while RlmN only performs a C2 methylation using the same mechanism of function |
