Enzymes Which of the following is false statement with regard to comparison between Serine and HIV proteases? Both use nucleophilic attack to hydrolyze the peptide bond Both require water to complete the catalytic cycle Both show specificity for certain amino acid sequences Both forms an acyl-enzyme intermediate Both use nucleophilic attack to hydrolyze the peptide bond Both require water to complete the catalytic cycle Both show specificity for certain amino acid sequences Both forms an acyl-enzyme intermediate ANSWER DOWNLOAD EXAMIANS APP
Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the size, shape, and charge of the active site or specificity pocket absence of water in the active site presence of a low-barrier hydrogen bond in the active site or specificity pocket proximity of Ser 195 to the active site or specificity pocket size, shape, and charge of the active site or specificity pocket absence of water in the active site presence of a low-barrier hydrogen bond in the active site or specificity pocket proximity of Ser 195 to the active site or specificity pocket ANSWER DOWNLOAD EXAMIANS APP
Enzymes In the enzyme-catalyzed reaction shown below, what will be the effect on substances A, B, C, and D of inactivating the enzyme labeled E2? A ---(E1)---> B ---(E2)---> C ---(E3)---> A, B, and C will still be produced, but not D A and B will still be produced, but not C or D A will still be produced, but not B, C, or D A, B, C, and D will all still be produced A, B, and C will still be produced, but not D A and B will still be produced, but not C or D A will still be produced, but not B, C, or D A, B, C, and D will all still be produced ANSWER DOWNLOAD EXAMIANS APP
