Bovine pro-phospholipase A2 (Mr = 14,520), trigonal, P3(1)21, a = b = 46.5, c = 102.0 A, one molecule per asymmetric unit, lambda (Cu K alpha) = 1.54 A. The model incorporating 895 protein atoms, two molecules of 2-methyl-2,4-pentanediol, and 60 solvent water molecules, was refined by restrained least squares to a residual R = 0.194 for 14,667 reflections from 5 to 1.6 A resolution.
牛前磷脂酶A2（分子量=14,520），呈三角晶系，空间群P3(1)21，a = b = 46.5，c = 102.0埃，每个不对称单位含一个分子，λ（铜Kα射线）= 1.54埃。该模型包含895个蛋白质原子、两个2-甲基-2,4-戊二醇分子和60个溶剂水分子，通过约束最小二乘法进行精修，对于5至1.6埃分辨率范围内的14,667个反射，残余R因子为0.194。
