WebNov 3, 2010 · Hexokinases (HKs) catalyze the first step in glucose metabolism. Of the three mammalian 100-kDa HK isoforms, HKI and II can bind to mitochondria and protect against cell death. HKIII does not bind mitochondria, and little is known about its regulation or cytoprotective effects. 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 the most important product. Hexokinase possesses the ability to transfer an inorganic … 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 vertebrates. The enzymes from yeast, plants and … 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 Hexokinases I and II can associate physically to the outer surface of the external membrane of mitochondria through specific binding to a porin, or voltage dependent anion channel. This association confers hexokinase direct access to ATP generated by … See more The intracellular reactions mediated by hexokinases can be typified as: Hexose-CH2OH + MgATP → Hexose-CH2O-PO 3 + MgADP + H where hexose-CH2OH represents any of several hexoses (like glucose) that contain an accessible … 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).
