7. Destroying the Trojan horse. Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β lactamase), an enzyme present in some resistant bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6kDa. The amount of penicillin hydrolyzed in 1 minute in a 10−ml solution containing 10−9 g of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. ✓4 529 a. Plot V0 versus [S] and 1/V0 versus 1/[S] for these data. Does penicillinase appear to obey Michaelis-Menten kinetics? If so, what is the value of KM ? b. What is the value of Vmax ? c. What is the turnover number of penicillinase under these experimental conditions? Assume one active site per enzyme molecule.
