Differential Role of the Protein Matrix on the Binding of a Catalytic Aspartate to Mg2+ vs Ca2+: Application to Ribonuclease H.
Dr. Lim, Carmay
J Am Chem Soc., Apr 23, 2013Divalent metal cations are essential cofactors for many enzyme functions. Although Mg2+ is the native cofactor in many enzymes such as ribonuclease H, its competitor Ca2+ may also bind to the enzyme but inhibit catalysis. Thus, the competition between Mg2+ and Ca2+ for a given metal-binding site in an enzyme and their effects on enzyme activity are of great interest. Most studies have focused on the interactions between Mg2+ or Ca2+ and the metal ligands in the first and sometimes second coordination shell.
