Kinetic and thermodynamic analysis defines roles for two metal ions in DNA polymerase specificity and catalysis
Magnesium ions play a critical role in catalysis by many enzymes and contribute to the fidelity of DNA polymerases through a two-metal ion mechanism. However, specificity is a kinetic phenomenon and the roles of Mg(2+) ions in each step in the catalysis have not been resolved. We first examined the...
