Antibiotic-resistant bacteria have an enzyme, penicillinase, that catalyzes the decomposition of the antibiotic. the molecular mass of penicillinase is 31200 g/mol. the turnover number of the enzyme at 28 °c is 2.00 × 103 s–1. if 4.10 μg of penicillinase catalyzes the destruction of 2.83 mg of amoxicillin, an antibiotic with a molecular mass of 364 g/mol, in 29.6 seconds at 28 °c, how many active sites does the enzyme have? assume that the enzyme is fully saturated under the conditions described above.
