DCK Recombinant Protein

Source : Escherichia Coli. DCK Human Recombinant fused with a 36 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 296 amino acids (1-260 a.a.) and having a molecular mass of 34.6kDa. The DCK is purified by proprietary chromatographic techniques. DCK (Deoxycytidine kinase) is a key enzyme in the salvage of deoxyribonucleosides and in the activation of clinically relevant nucleoside analogues. DCK is responsible for the 5`-phosphorylation of purine and pyrimidine deoxynucleosides to the corresponding monophosphates using ATP or UTP as phosphate donors. Deficiency of the DCK enzyme activity is linked to resistance to antiviral and anticancer chemotherapeutic agents, whereas increased DCK enzyme activity is linked to increased activation of these compounds to cytotoxic nucleoside triphosphate derivatives.
