Table 2 Specific activities of XR (xylose reductase), XDH (xylitol dehydrogenase), XK (xylulokinase), ADH (alcohol dehydrogenase), PDC (pyruvate decarboxylase), FBP (fructose-1,6-bisphosphatase), and TKL (transketolase) in the cells of analyzed O. polymorpha strains from third day of xylose alcoholic fermentation at 45 °C

From: Transcriptional activator Cat8 is involved in regulation of xylose alcoholic fermentation in the thermotolerant yeast Ogataea (Hansenula) polymorpha
