Abstract
A yeast cytosol is shown to contain two distinct activities that stimulate protein translocation across microsomal membranes. One activity was purified. It consists of two constitutively expressed 70K heat shock related proteins that increase the rate of translocation. Possible mechanisms of action of these proteins are discussed.
摘要
已证明酵母细胞溶质中含有两种不同的活性物质，它们能刺激蛋白质跨微粒体膜的转运。其中一种活性物质已被纯化。它由两种组成型表达的与70K热休克相关的蛋白质组成，可提高转运速率。文中讨论了这些蛋白质可能的作用机制。
