    Recoverin, a retinal calcium-binding protein of relative molecular mass (M(r)) 23K, participates in the recovery phase of visual excitation and in adaptation to background light. The Ca(2+)-bound form of recoverin prolongs the photoresponse, probably by blocking phosphorylation of photoexcited rhodopsin. Retinal recoverin contains a covalently attached myristoyl group or related acyl group at its amino terminus and two Ca(2+)-binding sites. Ca2+ binding to myristoylated, but not unmyristoylated, recoverin induces its translocation to bilayer membranes, indicating that the myristoyl group is essential to the read-out of calcium signals (calcium-myristoyl switch). Here we present the solution structure of Ca(2+)-free, myristoylated recombinant recoverin obtained by heteronuclear multidimensional NMR spectroscopy. The myristoyl group is sequestered in a deep hydrophobic pocket formed by many aromatic and other hydrophobic residues from five flanking helices.
