Overexpression of Mutant Galactose Permease (ScGal2_N376F) Effective for Utilization of Glucose/Xylose or Glucose/ Galactose Mixture by Engineered Kluyveromyces marxianus

Proton-motive force-driven D-galactose transport in plasma membrane vesicles from the yeast Kluyveromyces marxianus.

Galactose transport was studied in membrane vesicles, prepared by fusion of plasma membranes from the yeast Kluyveromyces marxianus with proteoliposomes containing beef heart cytochrome c oxidase as a proton-motive force-generating system. Sugar transport studies performed under nonenergized conditions revealed that, even at high protein to phospholipid ratios, not all vesicles contained a D-ga...

Towards enhanced galactose utilization by Lactococcus lactis.

Accumulation of galactose in dairy products due to partial lactose fermentation by lactic acid bacteria yields poor-quality products and precludes their consumption by individuals suffering from galactosemia. This study aimed at extending our knowledge of galactose metabolism in Lactococcus lactis, with the final goal of tailoring strains for enhanced galactose consumption. We used directed gen...

Congenital glucose galactose malabsorption.

Introduction Congenital glucose galactose malabsorption (CGGM) is a rare autosomal recessive disorder, which presents as a protracted diarrhoea in early neonatal life. It is due to a defect in sodium coupled transport of glucose and galac­ tose in the enterocyte (1). Diarrhoea in CGGM is osmotic, caused by accumulation of unabsorbed glucose and ga­ lactose in the intestine (2), which results in...

Glucose-galactose malabsorption.

A Case Report of Glucose-Galactose Malabsorption in Iranian Child

Introduction Glucose-Galactose Malabsorption (GGM) is an autosomal recessive and rare disorder of intestinal transport of glucose and sodium-glucose cotransporter type (SGLT1). Case Report Our patient is a 32-day-old boy who was examined for severe diarrhea and acidosis and was treated with GGMdiagnosis. A number of laboratory tests were performed on this patient as well as positive test for r...
