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