The penicillins are a class of antibiotics containing two hetereocyclic rings that interfere with the construction of cell walls by bacteria. The interference results from reaction of the penicillin with an amino group of a protein that closes gaps that develop during construction of the cell wall. The insides of the cell leak out, and the organism dies. A. Modify the structure of penicillin G below to suggest a reasonable product for the reactions of penicillin G with the amino group of a protein (abbreviated as R-NH2). If you accidentally delete a vital part of the structure, click the red arrows (# ) above the eraser to reset the original structure. CH3 COOH IK B. Penicillin-resistant bacteria secrete an enzyme (penicillinase) that catalyzes hydrolysis of the antibiotic faster than the antibiotic can attack the cell-wall proteins. Modify the structure below to propose a structure for the product of this hydrolysis. НН CH3 "СООН
