Protein surface charges and Ca2+ binding to individual sites in calbindin D9k: stopped-flow studies.

Biochemistry - 1 May 1990

Martin S R, Linse S, Johansson C, Bayley P M, Forsén S

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 kinetic methods, using the fluorescent calcium chelator Quin 2, and by 43Ca NMR methods. The first group of mutants...
