'''THREE-DIMENSIONAL STRUCTURE OF RECOVERIN, A CALCIUM SENSOR IN VISION'''<br />
'''THREE-DIMENSIONAL STRUCTURE OF RECOVERIN, A CALCIUM SENSOR IN VISION'''<br />


==Overview==
==Overview==
Recoverin, a recently discovered member of the EF hand superfamily, serves, as a calcium sensor in vision. We report here the crystal structure of, recombinant unmyristoylated recoverin at 1.9 A resolution. The four EF, hands of the protein are arranged in a compact array that contrasts with, the dumbbell shape of calmodulin and troponin C. A calcium ion is bound to, EF hand 3, while EF hand 2 can bind samarium but not calcium in this, crystal form. The other two EF hands have novel structural features that, prevent or impair calcium binding. A concave hydrophobic surface formed by, EF hands 1 and 2 may participate in the read out of calcium signals by, recoverin and its homologs.
