==CALPAIN DOMAIN VI APO==
-
The crystal structure of a Ca(2+)-binding domain (dVI) of rat m-calpain, has been determined at 2.3 A resolution, both with and without bound Ca2+., The structures reveal a unique fold incorporating five EF-hand motifs per, monomer, three of which bind calcium at physiological calcium, concentrations, with one showing a novel EF-hand coordination pattern., This investigation gives us a first view of the calcium-induced, conformational changes, and consequently an insight into the mechanism of, calcium induced activation in calpain. The crystal structures reveal a dVI, homodimer which provides a preliminary model for the subunit dimerization, in calpain.
