Crystals of sarcoplasmic calcium-binding proteins from Nereis diversicolor have been grown from solutions of ammonium sulfate. The crystals are monoclinic, space group P2(1); the axes are a = 43.65 (1), b = 56.05 (1), c = 65.77 (1) A, and beta = 92.58 (2) degrees. The crystals are quite stable to x-rays and diffract beyond 2.5 A resolution. The asymmetric unit contains two protein molecules.
来自多毛纲沙蚕的肌浆钙结合蛋白晶体已从硫酸铵溶液中生长出来。这些晶体为单斜晶系,空间群为P2(1);轴长分别为a = 43.65 (1)、b = 56.05 (1)、c = 65.77 (1) Å,β = 92.58 (2) 度。这些晶体对X射线相当稳定,衍射分辨率超过2.5 Å。不对称单元包含两个蛋白质分子。
