PhrB Recombinant Protein

Source : Escherichia Coli. It produced in E.coli is a single, non-glycosylated polypeptide chain containing 495 amino acids (1-472) and having a molecular mass of 56.1kDa.phrB is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Deoxyribodipyrimidine photo-lyase (phrB) is a member of the DNA photolyase class-1 family. phrB takes part in repair of UV radiation-induced DNA damage. phrB catalyzes the light-dependent monomerization (300-600 nm) of cyclobutyl pyrimidine dimers (in cis-syn configuration), which are formed between closest bases on the same DNA strand upon exposure to ultraviolet radiation.
