Proton NMR assignments indicate that this mutant adopts the canonical EF hand fold (binding with side chains, not the backbone). However, the calcium-loaded state seems to adopt the same global fold ("closed") as the wildtype protein, in which the first binding loop binds calcium with mostly its backbone atoms.
