Arguments are presented leading to the conclusion that two major factors contribute to the potency of inhibition of DNA-polymerase activity by chain-terminating nucleotides. The relative significance of these factors varies with the reaction conditions, particularly with the length of the template and the concentration ratio of enzyme (reverse transcriptase or other DNA polymerase) to primer. It is concluded that potent inhibition of HIV-reverse transcriptase activity under typical in vitro and in vivo conditions arises from different features of the interaction of chain terminators with the enzyme. A new method of testing for the parameter important under in vivo conditions is suggested.
