WebOct 12, 2024 · In Escherichia coli, DNA cytosine methyltransferase (Dcm) methylates the second cytosine in the sequence 5'CCWGG3' generating 5-methylcytosine. Dcm is not associated with a cognate restriction enzyme, suggesting Dcm impacts facets of bacterial physiology outside of restriction-modification systems. Other than gene expression … WebApr 14, 2024 · Hence, novel therapies based on an increased understanding of the mechanistic underpinnings of GBM are desperately needed. In this study, we show that elevated expression of 28S rRNA (cytosine-C(5))-methyltransferase NSUN5, which methylates cytosine 3782 of 28S rRNA in GBM cells, is strongly associated with the …

There is substantial variability in TPMT enzyme activity between individuals, and it has been found that this variability can be attributed to polymorphisms in the TPMT gene.
