斑头雁(Auser Indicus)氧合血红蛋白的结晶和X射线的初步分析

CRYSTALLIZATION OF BARHEADED GOOSE (ANSER INDICUS) OXYHEMOGLBIN AND PRELIMINARY X-RAY STUDIES

本文报道了以聚乙二醇溶液为沉淀剂培养斑头雁氧合血红蛋白晶体.经X射线旋进照相法分析确定,晶体属四方晶系,空间群为P4_22_12,晶胞参数a=b=81.5(?),c=106.4(?),α=β=γ=90V=706735.4(?)~3.每个不对称单位内包含半个四聚体分子.

Single crystals were obteined from polyethylene Glycol solution. The space group is P42212 with unit cell dimensions a = b = 81.5A and c= 106.4A, 1.2 tetramers in the crystallographic asymmetric unit.
