DNA restriction enzymes from Takara Bio are unsurpassed in quality and purity. We’ve been producing them for over 30 years and were the first manufacturers to offer commercially available restriction enzymes in Japan. Each lot of every DNA restriction enzyme undergoes stringent quality control tests. Takara Bio DNA restriction enzymes are supplied with optimized buffers that provide maximum activity during restriction enzyme digestion. Visit our Restriction Enzyme Applications pages for information on how to digest DNA, relative activity in each Universal Buffer, star activity, buffers for double digestion, effects of DNA methylation, how to inactivate enzymes, and more.
Methylation Dependent Restriction Enzyme
McrBC specifically cleaves DNA containing methyl cytosine (mC : 5-hydroxymethylcytosine, 5-methylcytosine, 4-methylcytosine) preceded by a purine nucleotide (Pu : A or G). DNA cleavage by McrBC requires at least two PumC sites within a distance of 40 – 2,000 bp. McrBC requires GTP for cleavage.
