Fig. 1From: Directed evolution and secretory expression of xylose isomerase for improved utilisation of xylose in Saccharomyces cerevisiaeSelection of optimal translational fusion partner (TFP) for xylose isomerase (xylA) secretion in S. cerevisiae. a SDS-PAGE and b western blot analysis using anti-6xHIS antibody against xylA secreted by the TFP system. c Amount of xylose consumed after 40Â h cultivation in YPDX medium. The xylA protein band is indicated by an arrow. M: protein size markerBack to article page
