Deoxycytidine kinase from rabbit kidney cells infected with herpes simplex virus type 1 or 2.
When rabbit kidney cells were infected with herpes simplex virus type 1 (strain Seibert) or herpes simplex virus type 2 (strain 316D), deoxycytidine kinase (CdR kinase) activity, assayed at 38 degrees, increased 5- to 15-fold relative to controls. The CdR kinase activity induced by type 2 virus was more thermolabile than the enzyme activity induced by type 1 virus. When CdR kinase activity was assayed at various temperatures between 0.5 and 38 degrees, maximum activity for type 1 enzyme was obtained at 16 degrees while maximum activities for host and type 2 enzymes were obtained at 38 degrees. Both type 1 and type 2 induced CdR kinase activities eluted at the same positions as deoxythymidine kinase activities on a Sephadex G-100 column. The estimated mol wt for HSV-1 (Seibert) and HSV-2 (316D) induced CdR kinases are 67,000 and 60,000, respectively.
