 AB    HIV-1 reverse transcriptase (RT) was found to increase the activity of
       HIV-1 proteinase in vitro and in eukaryotic cells. The effect of RT on
       proteinase activity was dose-dependent and independent of pH or salt
       concentration. The cleavage of sequences corresponding to all the
       naturally occurring cleavage sites that could be tested in vitro was
       enhanced. The effect of RT on cleavage was greatest at the cleavage site
       between RT and integrase. The enhancement of viral proteinase activity
       by the virus RT may contribute to regulation of the order and/or
       efficiency of cleavage at different sites during virus replication and
       maturation.
