The hexose transporter family of Saccharomyces cerevisiae
- 596 Downloads
Saccharomyces cerevisiae accomplishes high rates of hexose transport. The kinetics of hexose transport are complex. The capacity and kinetic complexity of hexose transport in yeast are reflected in the large number of sugar transporter genes in the genome. Twenty hexose transporter genes exist in S. cerevisiae. Some of these have been found by genetic means; many have been discovered by the comprehensive sequencing of the yeast genome. This review codifies the nomenclature of the hexose transporter genes and describes the sequence homology and structural similarity of the proteins they encode. Information about the expression and function of the transporters is presented. Access to the sequences of the genes and proteins at three sequence databases is provided via the World Wide Web.
