3. (а) 0.0050 M operate at one-quarter of its maximum rate? At what substrate concentration would an enzyme with a kcat of 30.0 s-1 and a Km of (b) trations [So]: ½ Km, 2 KM, and 10 KM. Determine the fraction of Vmax that would be obtained at the following substrate concen- (c) 1 (HIV-1) has been the object of innumerable studies to develop effective chemotherapeutic agents. It has been shown that p6* known as the late assembly protein is an inhibitor of HIV protease. An assay was developed using an artificial polypeptide substrate containing a p-nitrophenylalanine residue at the cleavage point that undergoes a small change in absorption at 295 nm upon bond hydrolysis that could be followed spectrophotometrically. The cleavage of the peptide bond is shown schematically on the right. Results of the assay are given in the table below. The protease of the human immunodeficiency virus- Lys NH2 Ala Nle Arg Ala Val-Nle-NH-CH-Ċ–NH-Glu CH2 Lys NH2 Ala NO2 Nle Arg H2Ó N HIV-1 protease Ala Vo…
