Cytosine 5 -triphosphate
Web5-Methylcytosine (5mC) is an enzymatically produced modified cytosine base that has been known to exist in mammalian DNA for about 70 years. These decades of research have provided important clues as to its presumed functional role but there is no complete understanding yet. The function of this chemical varies significantly among species: • In bacteria, 5-methylcytosine can be found at a variety of sites, and is often used as a marker to protect DNA from being cut by native methylation-sensitive restriction enzymes. • In plants, 5-methylcytosine occurs at CpG, CpHpG and CpHpH sequences (where H = A, C or T).
