'''CRYSTAL STRUCTURE OF RECOMBINANT BOVINE NEUROCALCIN DELTA AT 2.4 ANGSTROMS'''<br />


==Overview==
==CRYSTAL STRUCTURE OF RECOMBINANT BOVINE NEUROCALCIN DELTA AT 2.4 ANGSTROMS==
The crystal structure of calcium-bound unmyristoylated bovine neurocalcin, from Escherichia coli has been determined at 2.4 A resolution. The, three-dimensional structure reveals a highly compact structure consisting, of: (i) two pairs of calcium-binding EF-hands (EF1-EF2 and EF3-EF4); (ii), a calcium ion bound at EF2, EF3 and EF4 sites; and (iii) an EF1-hand that, is disabled from calcium-binding due to a Cys-Pro sequence in the, Ca2+-binding loop. The crystal structure of neurocalcin resembles, photoreceptor recoverin in overall topology, however its EF2- and, EF4-hands differ. Recently, neurocalcin in the calcium-bound state has, been shown to stimulate mammalian rod outer segment membrane guanylate, cyclase. A possible site for cyclase activity based on the, three-dimensional structure is discussed.
