Four kinds of transporters, HXT1 and HXY7 from Saccharomyces cerevisiae, and GXF1 and GXS1 from Candida intermedia, were overexpressed in xylose-metabolizing S. cerevisiae harboring a xyloseisomerase-based pathway. Overexpression of transporter enhanced sugar consumption and ethanol production, and GXF1 was efficient for ethanol fermentation from both glucose and xylose.
四种转运蛋白，来自酿酒酵母的 HXT1 和 HXY7，以及中间假丝酵母的 GXF1 和 GXS1，在含有木糖异构酶途径的木糖代谢酿酒酵母中过表达。转运蛋白的过表达增强了糖的消耗和乙醇的生产，并且 GXF1 能够有效地从葡萄糖和木糖发酵生产乙醇。
