Proteolysis is the type of protein destruction for examle in proteosomes by
action of enzymes proteases (trypsin, chymotrypsin, pepsin, peptidases), the
type of action of this enzymes is the destruction of peptide bond between
the specific amino acids. Ka is the constant of dissotiation between the
enzyme an substrate, if your substrate is full of Mg2+ its Ka will be higher
and towards. It depends upon the ionic power of your buffer
