Abstract excerpt

The kinetics of calcium dissociation from two groups of site-specific mutants of calbindin D9k--a protein in the calmodulin superfamily with two Ca2+ sites and a tertiary structure closely similar to that of the globular domains of troponin C and calmodulin--have been studied by stopped-flow kine...
