WebThis study was performed to determine how physiological hyperinsulinemia regulates the activities of hexokinase (HK), glycogen synthase (GS), and GLUT-4 in human skeletal muscle in vivo. We determined mRNA abundance, protein content, and activities for these proteins in muscle biopsies before and after a hyperinsulinemic clamp in normal subjects. Wikipedia See more A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars), forming hexose phosphate. In most organisms, glucose is the most important substrate for hexokinases, and glucose-6-phosphate is … See more The intracellular reactions mediated by hexokinases can be typified as: Hexose-CH2OH + MgATP → Hexose-CH2O-PO 3 + MgADP + H where hexose … See more Most bacterial hexokinases are approximately 50 kDa in size. Multicellular organisms including plants and animals often have more than one hexokinase isoform. Most are about 100 kDa in size and consist of two halves (N and C terminal), which … See more Glucose is unique in that it can be used to produce ATP by all cells in both the presence and absence of molecular oxygen (O2). The … See more Genes that encode hexokinase have been discovered in every domain of life, and exist among a variety of species that range from bacteria, yeast, and plants to humans and other See more Phosphorylation of a hexose such as glucose often limits it to a number of intracellular metabolic processes, such as glycolysis or glycogen synthesis. This is because phosphorylated hexoses are charged, and thus more difficult to transport out of a cell. See more There are four important mammalian hexokinase isozymes (EC 2.7.1.1) that vary in subcellular locations and kinetics with respect to different substrates and conditions, and physiological function. They were designated hexokinases A, B, C, and D on the … See more
