Cloned (Comment) Organism
overexpression of HXK1 in a laboratory strain of Saccharomyces cerevisiae (W303-1A) accelerates fructose consumption more than glucose consumption, but overexpression in a wine yeast strain (VIN13) reduces fructose consumption less than glucose consumption Saccharomyces cerevisiae

additional information Saccharomyces cerevisiae G/F discrepancy in Saccharomyces cerevisiae is not related to the maximal hexokinase activity in vitro with glucose or fructose as substrate or to the ratio between the Km values for glucose and fructose phosphorylation but might rather be related to the actual fructose phosphorylating activity at physiological fructose levels in vivo ?
