Figure 2From: Engineering of xylose reductase and overexpression of xylitol dehydrogenase and xylulokinase improves xylose alcoholic fermentation in the thermotolerant yeast Hansenula polymorphaAlignment of XRs cofactor binding site sequences from several xylose-utilizing yeasts against the H. polymorpha XYL1 sequence. Conserved sequences are in bold. Underlined amino acids were changed (K → R and N → D).Back to article page
