Renin belongs to a class of enzymes called aspartyl proteases in which aspartate plays a catalytic role similar to serine in chymotrypsin. Renin inhibitors could potentially be used to treat high blood pressure. Two aspartate residues in the renin active site, Asp 32 and Asp 215, constitute a catalytic dyad, rather than the catalytic triad found in chymotrypsin. Select the correct reaction mechanism for peptide hydrolysis catalyzed by renin.

Residential construction is expanding in florida, the expansion has caused fragmentation of habitats, one of the results of the increased construction is a decrease in the number of large predators such as the coyote, black bear and pool panther, which will be the most immediate local result of this fragmentation? 1)large predators will become extinct 2)decrease in middle sized predators 3)increase in population of top carnivores 4)increase in population of prey species
