This part is a gene which encoding a cellobiose transporter(CDT-1).

This part is a gene which encoding a cellobiose transporter(CDT-1). Assimilate cellobiose into intracellular. In our project, we contract an engineered strain to use cellobiose. We all know that S. cerevisiae cannot ferment the cellodextrins naturally released by cellulases and require cellulase cocktails supplemented by β-glucosidase to quantitatively produce fermentable glucose. Cellobiose is not catabolized by S. cerevisiae and is not accumulated in the cytoplasm. So we express a functional cellodextrin transport system(CDT-1) from N. crassa allow S. cerevisiae to grow with cellobiose as the sole carbon source. CDT-1 is high-affinity cellobiose transporters, with Michaelis constant (Km) values of 4.0T0.3mM, respectively. Cellobiose transport by CDT-1 is inhibited by excess cello-triose, and CDT-1 activity is also inhibited by cellotetraose. What's more, the combinations of CDT-1 with GH1-1 constitute fully functional cellodextrin transport systems. We have constructed an engineered bacterium that can be used as a carbon source, which can be used to produce ethanol by fermentation of fiber sugars, and the following are our experimental results.
