site-directed mutagenesis, introduction of multiple site-directed mutations in the coenzyme-binding pocket of Galactocandida mastotermitis XDH to enable activity with NADP+, which is lacking in the wild-type enzyme, genetic metabolic engineering for improvement of xylose metabolism and fermentation in wild-type Saccharomyces cerevisiae strains, which are not able to naturally metabolize D-xylulose, overview |

| 1.1.1.9 | D207A/I208R/F209S |
mutant bearing a reversal of coenzyme specificity from NAD+ to NADP+ is introduced into Saccharomyces cerevisiae. kcat/Km (NAD+): 181 l/min/mmol, kcat/Km (NADP+): 2790 l/min/mmol, Km (xylitol in the presence of NAD+): 31.1 mM, NADP+-dependent activity: 0.782 U/mg, NAD+-dependent activity: 0.271 U/mg. In xylose fermentation a large decrease in xylitol and glycerol yield is shown, while the xylose consumption and ethanol yield are decreased |
