Acetylene hydratase is a tungsten-containing hydroxylase that converts acetylene to acetaldehyde in a unique reaction that requires a strong reductant. The subsequent disproportionation of acetaldehyde yields acetate and ethanol. Crystals of the tungsten/iron-sulfur protein acetylene hydratase from Pelobacter acetylenicus strain WoAcy 1 (DSM 3246) were grown by the vapour-diffusion method in an N2/H2 atmosphere using polyethylene glycol as precipitant. Growth of crystals suitable for X-ray analysis strictly depended on the presence of Ti(III) citrate or dithionite as reducing agents.
乙炔水合酶是一种含钨的羟化酶,它在一个需要强还原剂的独特反应中将乙炔转化为乙醛。随后乙醛的歧化反应产生乙酸盐和乙醇。来自乙酰丙酸杆菌菌株WoAcy 1(DSM 3246)的钨/铁硫蛋白乙炔水合酶晶体通过气相扩散法在N2/H2气氛中使用聚乙二醇作为沉淀剂生长。适合X射线分析的晶体生长严格依赖于柠檬酸钛(III)或连二亚硫酸盐作为还原剂的存在。
