Abstract
The Escherichia coli protein YodA was overexpressed, purified and crystallized in several crystal forms. The function of this protein is not known, although it has been identified under conditions of bacterial stress. Three of the four crystal forms were obtained in the presence of divalent cations (zinc, nickel and cadmium), suggesting that YodA may be a metal-binding protein.
摘要
大肠杆菌蛋白YodA被过量表达、纯化，并以几种晶体形式结晶。尽管该蛋白是在细菌应激条件下被鉴定出来的，但其功能尚不清楚。四种晶体形式中的三种是在二价阳离子（锌、镍和镉）存在的情况下获得的，这表明YodA可能是一种金属结合蛋白。
