Abstract
The specific binding activity to [14C]thiamine was found to be located in hte plasma membrane of Saccharomyces cerevisiae. The activity was inhibited by several thiamine analogs and it was hardly detectable in the plasma membrane from a thiamine transport mutant of Saccharomyces cerevisiae. Some properties of the thiamine-binding activity of yeast plasma membrane are discussed in connection with those of the thiamine transport system.
摘要
发现对[14C]硫胺素的特异性结合活性位于酿酒酵母的质膜中。该活性受到几种硫胺素类似物的抑制，并且在酿酒酵母硫胺素转运突变体的质膜中几乎检测不到。结合硫胺素转运系统的特性对酵母质膜硫胺素结合活性的一些特性进行了讨论。
