Pyrimidine deoxyribonucleoside kinase (thymidine kinase [TK]) was purified from 2 herpes simplex virus type 1 (HSV-1)-transformed TK-deficient mouse (LMTK-) cell lines and from LMTK- cells infected with HSV-1 mutant viruses coding for variant TK enzymes. These preparations exhibited normal or variant virus-induced thymidylate kinase activities correlating with their relative TK activities. Neither virus-induced activity was detected in LMTK- cells infected with an HSV-1 TK-deficient mutant. HSV-1 thymidylate kinase activity and TK activity are mediated by the same protein.
