Critical Reviews in Biochemistry and Molecular Biology, 1993
Transport of sugars is a fundamental property of all eukaryotic cells. Of particular importance is the uptake of glucose, a preferred carbon and energy source. The rate of glucose utilization in yeast is often dictated by the activity and concentration of glucose transporters in the plasma membrane.

Sugar Transport & Sugar Sensing In Grape
2009The ripening of grape berries is accompanied by a massive accumulation of soluble sugars, and by the synthesis and accumulation of a wide range of phenolic compounds and aroma precursors. These processes play major roles in the quality of the berries and wine. Sugars are accumulated in the vacuoles of flesh (mesocarp) cells, which account for 65 to 91 %

Regulation of intestinal sugar transport
Physiological Reviews, 1997The recent surge in knowledge of cellular and molecular mechanisms of intestinal sugar transport has fueled an enormous interest in adaptive mechanisms regulating sugar transport. We first review several functional considerations that help us interpret the different patterns of adaptation for different nutrients.

Sugar transport in Coprinus cinereus
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1979Two transport systems for glucose were detected: a high affinity system with a Km of 27 muM, and a low affinity system with a Km of 3.3 mM. The high affinity system transported glucose, 2-deoxy-D-glucose (Km = 26 muM), 3-O-methylglucose (Km = 19 muM), D-glucosamine (Km = 652 muM), D-fructose (Km = 2.3 mM) and L-sorbose (Km = 2.2 mM).

Sugar transport in beef erythrocytes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 19721. 1. The entry of sugar into beef erythrocytes was found to be facilitated by a saturable, passive process with unusually high affinity for d-glucose and d-3-O-methylglucose, the Michaelis constants for these two sugars being 0.09 and 0.17 mM respectively.

‘Active’ Sugar Transport In Eukaryotes
Journal of Experimental Biology, 1994ABSTRACT Sugar transporters in prokaryotes and eukaryotes belong to a large family of membrane proteins containing 12 transmembrane alpha-helices. They are divided into two classes: one facilitative (uniporters) and the other concentrative (cotransporters or symporters).

Sugar transport: Occurrence of trehalase activity in sugar cane
Planta, 1969Trehalase activity was detected in extracts of roots, leaves, and stalk tissue from sugar cane. The enzyme was not bound to cell particulates, and had a pH optimum of 6.2 and a Michaelis constant for trehalose of 1×10(-4) M. The level of enzyme detected in mature stalk tissue was too low to account for glucose transport into tissue slices.

1982
The classical experiments of Monod’s group (Cohen and Monod 1957) have made biochemists aware of the importance of transport as the first biochemical reaction in the metabolism of a substance. Though the transport of substances through membranes occurs without a permanent alteration of its chemical structure (there are only a few exceptions), the ...

Intestinal sugar transport in experimental diabetes
Diabetes, 1981The increased sugar transport was examined in the isolated small intestine of streptozotocin-diabetic rats. In the small intestine of these animals, the rate of glucose absorption in vivo is slightly increased, but not that of galactose of 3-O-MG (3-O-Methylglucose); however, in the isolated small intestine, the mucosal-toserosal but not the serosal-to-

Sugar transporters in plant biology
Current Opinion in Plant Biology, 1999Sugar transporters are key players in many fundamental processes in plant growth and development. Recent results have identified several new transporters that contribute to a wide array of physiological activities, and detailed molecular analysis has provided exciting insights into the structure and regulation of these essential membrane proteins.
