Abstract

Ca$^{2＋}$ is one of the most common metal ions associated with proteins, playing more or less well-defined functional roles in biological activities. In protease, the presence of $Ca^{2＋}$ slows down autolysis and enhances thermal stability. Subtilisin, one of the best studied proteases, is known to have two $Ca^{2＋}$ -binding sites.(omitted)
