Enzymes The role of Asp 102 and His 57 during trypsin catalysis is to clamp the substrate into the active site function as a proton shuttle neutralize the charge on the other's side chain keep the specificity pocket open clamp the substrate into the active site function as a proton shuttle neutralize the charge on the other's side chain keep the specificity pocket open ANSWER DOWNLOAD EXAMIANS APP
Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule ANSWER DOWNLOAD EXAMIANS APP
Enzymes Which of the common features are shared between serine and aspartate proteases?

Enzymes The cleavage specificity of trypsin and chymotrypsin depend in part on the presence of a low-barrier hydrogen bond in the active site or specificity pocket size, shape, and charge of the active site or specificity pocket proximity of Ser 195 to 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 size, shape, and charge of the active site or specificity pocket proximity of Ser 195 to the active site or specificity pocket absence of water in the active site ANSWER DOWNLOAD EXAMIANS APP
