3. The table on the last page compares for each of four different proteolytic enzymes the chemical bonding structure of a classical substrate with the structures of two competitive inhibitors. For each substrate structure an arrow indicates the position of the scissile bond, i.e., the bond that is cleaved through catalytic action. For each enzyme, one of the inhibitors is a classical competitive inhibitor while the other is a transition-state inhibitor analog. While ordinary competitive inhibitors are associated with (dissociation) inhibitor equilibrium con- stants of ~10-3 to 10-6 M, transition-state analogs exhibit inhibitor constants ≤ 10-⁹ M. (a) For each enzyme draw a circle around those parts of the substrate that account for specificity of substrate recognition. (b) For each enzyme identify the transition-state inhibitor analog by drawing a circle around it and give a brief explanation of why it mimics the structure of the transition-state species. (c) Draw a "generic"…

Rhinovirus, the most common cause of colds, do not have a lipid envelope. Compared to enveloped viruses these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.
