Cytosine 5 -triphosphate
WebApr 12, 2024 · The main innovation of this elegant method lies in using a two-base coding strategy for the four canonical bases plus 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC). WebWe also found that C5 cytosine methylation greatly enhanced N-OH-4-ABP binding at CpG sites, and that two mutational hotspots at CpG sites, codons 175 and 248, became preferential binding sites for N-OH-4-ABP only after being methylated. These results suggest that both the unique DNA binding specificity of 4-ABP and cytosine methylation ...
