Molecular dynamics study of Ca(2+) binding loop variants of silver hake parvalbumin with aspartic acid at the "gateway" position.

Abstract excerpt

The helix-loop-helix (i.e., EF-hand) Ca(2+) ion binding motif is characteristic of a large family of high-affinity calcium ion binding proteins, including the parvalbumins, oncomodulins and calmodulins. In this work we describe a set of molecular dynamics computations on the major parvalbumin from the silver hake (SHPV-B) and on functional fragments of this protein, consisting of the first four helical regions...
