The TorD family of specific chaperones is divided into four subfamilies dedicated to molybdoenzyme biogenesis and a fifth one, exemplified by YcdY of Escherichia coli, for which no defined partner has been identified so far. We propose that YcdY is the chaperone of YcdX, a zinc protein involved in the swarming motility process of E. coli, since YcdY interacts with YcdX and increases its activity in vitro.
TorD 家族的特定伴侣蛋白分为四个亚家族,专门用于钼酶的生物发生,还有第五个亚家族,以大肠杆菌的 YcdY 为例,到目前为止还没有确定其明确的伴侣蛋白。我们提出 YcdY 是 YcdX 的伴侣蛋白,YcdX 是一种参与大肠杆菌群集运动过程的锌蛋白,因为 YcdY 与 YcdX 相互作用,并在体外增加其活性。
