    摘要: Compositions and methods for identifying agents that inhibit protease activity are provided. In particular, polynucleotides, recombinant expression vectors, and host cells are provided that may be used in a bacterial cell-based assay for identifying agents that are inhibitors of protease activity, such as inhibitors of HIV protease activity. The bacterial cells express a precursor of a protease and encode a reporter polypeptide that contains a protease recognition sequence, which can be cleaved by the mature, catalytically active protease such that the reporter activity of the reporter polypeptide is decreased or eliminated.
