A methylase which alters the ribosomal RNA binding site of the antibiotic linezolid causes cross-resistance to other antibiotics that act on the ribosomal RNA. Plasmid vectors capable of transmitting this gene are a cause of potentially dangerous cross resistance. Examples of methyltransferase enzymes relevant to … See more Methyltransferases are a large group of enzymes that all methylate their substrates but can be split into several subclasses based on their structural features. The most common class of methyltransferases … See more Genetics Methylation, as well as other epigenetic modifications, affects transcription, gene stability, and See more As with any biological process which regulates gene expression and/or function, anomalous DNA methylation is associated with genetic … See more In human cells, it was found that m5C was associated with abnormal tumor cells in cancer.
