Question

Quizplus · Accepted Answer

The main difference among the active sites of all serine proteases is the size and charge of the pocket at the active site. While all serine proteases do have a serine residue at the active site that is involved in the hydrolysis of the peptide bond, the differences in the size and charge of the pocket at the active site determine the specificity of the protease for different substrates. Histidine and aspartate residues may also be present in the active site, but their presence is not the main distinguishing feature among serine proteases.
