Fig. 2From: Improving pentose fermentation by preventing ubiquitination of hexose transporters in Saccharomyces cerevisiae Growth of strain DS68625 over-expressing Hxt36 (a) and Hxt36 N367A (b) on 2 % d-xylose. Different variants of Hxt36 were used in which the N- and C-terminal lysine residues were replaced by arginine residues (open square wt, open circle 1K, filled square 3K, filled circle 5K, and filled triangle 8K)Back to article page
