Isolation of deoxycytidine kinase from Ehrlich carcinoma cells by affinity chromatography based on a substrate analog, 2'-C-cyano-2'-deoxy-1-beta-D-arabinofuranosyl-N4-palmitoylcytosine++ +

Abstract

Deoxycytidine kinase from Ehrlich carcinoma cells was purified 10400-fold by ammonium sulfate fractionation and affinity chromatography using Sepharose 4B coupled to 2'-C-cyano-2'-deoxy-1-beta-D-arabinofuranosyl-N4-palmitoylcytosine , with a yield of 45%. The purified enzyme preparation showed a single major band with a molecular weight of 32000 on SDS-PAGE. The enzyme phosphorylated deoxyadenosine, deoxyguanosine, cytidine, and several deoxycytidine analogues as well as deoxycytidine. Also, the kinetic parameters of the enzyme for the substrates were estimated.
