Mutational analysis of a native substrate of the HIV-1 proteinase.


The purpose of this study was to define further the determinants of substrate specificity of HIV-1 PR. Rather than using small peptides, we used an in vitro system which permitted us to evaluate the effect of a mutated site within the context of its natural precursor. We made single-amino-acid substitutions around two sites which are processed by the HIV-1… (More)
