 AB    We have studied the effects of two non-nucleoside reverse transcriptase
       inhibitors (NNRTI), nitrophenyl phenyl sulfone (NPPS) and a potent
       derivative of oxathiin carboxanilide (UC-38), on enzymatically active
       molecular chimeras composed of complementary segments of the reverse
       transcriptases (RTs) of human immunodeficiency virus type 1 (HIV-1) and
       -2 (HIV-2). The substances inhibit only the DNA polymerase activity of
       HIV-1 RT with no effect on HIV-2 RT. The results suggest that there is a
       protein segment located between residues 158 and 190 that is critical
       for the inhibition by both compounds. However, there is probably a
       second segment that resides between residues 192 and 202, as in the case
       of NPPS, or residues 203 and 224, as in the case of UC-38, that is also
       crucial for the sensitivity of HIV-1 RT to both inhibitors.
