Abstract

The invention is directed to compositions to screen for compounds, e.g., small molecules or drugs, that can modulate or inhibit enzymes, e.g., proteases, such as viral proteases, e.g., HIV proteases; and methods for making and using these compositions. In alternative embodiment, the invention provides compositions and methods for identifying compositions, e.g., drug molecules that can modulate or inhibit enzymes, e.g., proteases, proteinases or peptidases or the like, e.g., HIV proteases. In alternative embodiments, the invention provides cell-based assays to screen for compositions, e.g., small molecules or drugs, that modulate or inhibit or modify the activity of enzymes such as proteases, proteinases or peptidases or the like, such as calcium-dependent protein convertases involved in HIV envelop protein processing, including cleavage of the HIV gp160 envelope precursor, resulting in gp120 and gp41 envelope products. In alternative embodiment, the compositions and methods of the invention are adapted for high through-put or multiplexed screening of compounds, e.g., drug molecules that can modulate or inhibit enzymes.
