Sigma-Aldrich Pvurts1I 5-Hmc Endonuclease

35 kDa

PvuRts1I is an enzyme isolated from the gram negative bacterium Proteus vulgaris that can specifically digest DNA containing 5-hmC (Szwagierczak et al., Nucleic Acids Research, 2011) while leaving cytosine and 5-mC intact. This endonuclease can be used to analyze 5-hmC patterns in mammalian genomes by cleave cutting both glucosylated and non-glucosylated 5-hmC containing DNA sequences.

Research studies of DNA methylation and gene expression support the presence of 5-hydroxymethylcytosine (5-hmC) as a sixth base in mammalian genomes. 5-hmC is generated by Ten Eleven Translocation (TET) family of enzymes through oxidation of 5-methylcytosine (5-mC). Chemically, 5-hmC differs from 5-mC by the presence of a hydroxyl on the methyl group at position 5 of cytosine.
