Three different regulatory mechanisms enable yeast hexose transporter (HXT) genes to be induced by different levels of glucose.

Molecular and cellular biology - 1 Mar 1995

Ozcan S, Johnston M

Abstract excerpt

The HXT genes (HXT1 to HXT4) of the yeast Saccharomyces cerevisiae encode hexose transporters. We found that transcription of these genes is induced 10- to 300-fold by glucose. Analysis of glucose induction of HXT gene expression revealed three types of regulation: (i) induction by glucose independent of sugar concentration (HXT3); (ii) induction by low levels of glucose and repression at high glucose...
