【 摘 要 】
The hexose transporter family of Saccharomyces cerevisiae comprises 18 proteins (Hxt1–17, Gal2). Here, we demonstrate that all these proteins, except Hxt12, and additionally three members of the maltose transporter family (Agt1, Ydl247, Yjr160) are able to transport hexoses. In a yeast strain deleted for HXT1–17, GAL2, AGT1, YDL247w and YJR160c, glucose consumption and transport activity were completely abolished. However, as additional deletion of the glucose sensor gene SNF3 partially restored growth on hexoses, our data indicate the existence of even more proteins able to transport hexoses in yeast.
