DT 9404 AU Lowy I; Caruso M; Goff SP; Klatzmann D; Department of Medicine, Columbia University, New York, New York; 10032. SO Virology. 1994 Apr;200(1):271-5. Unique Identifier : AIDSLINE MED/94174725 AB In this report, we provide evidence that the cellular thymidine kinase activity is required for the inhibition of HIV replication by zidovudine (AZT) in lymphocytes. The HSV-1 thymidine kinase protein is not able to substitute for the cellular enzyme, in accord with in vitro data that AZT is poorly phosphorylated by the HSV-derived activity.
