Single crystals of glucose dehydrogenase from the archaebacterium Thermoplasma acidophilum were obtained using the hanging-drop vapour diffusion method and polyethylene glycol as a precipitant in the presence of NADP+ at pH 5.4. The crystals belong to the hexagonal space group P6122 or P6522, with unit cell dimensions a = b = 121.9 angstrom, c = 229.6 angstrom and with two molecules in the asymmetric unit.
采用悬滴气相扩散法,以聚乙二醇作为沉淀剂,在pH 5.4且存在NADP⁺的条件下,获得了嗜热嗜酸栖热菌葡萄糖脱氢酶的单晶。这些晶体属于六方空间群P6₁22或P6₅22,晶胞参数a = b = 121.9埃,c = 229.6埃,不对称单元中有两个分子。
