Values in parentheses are the percentage of the individual catalytic class in the protease complement. aThe percentage of the whole genome that encodes putative proteases. bThe distributions of T. thermophila and P. falciparum are based on Eisen et al. [11] and Wu et al. [60], respectively. The distributions of the other model organisms are based on the results published in Merops database.
