Heksokinaasi
Webhexokinase: [noun] any of a group of enzymes that accelerate the phosphorylation of hexoses (as in the formation of glucose-6-phosphate from glucose and ATP) in carbohydrate metabolism. WebHexokinase is known to have 4 different types, which are controlled by different genes on different chromosomes. Taking the human body as an example, Hexokinase II is controlled by a gene on chromosome 2, hexokinase III is controlled by a gene on chromosome 5, and hexokinase IV is controlled by a gene on chromosome 7 (also called glucokinase).

Heksokinaasi on entsyymi, joka katalysoi heksoosisokereiden fosforylaatiota. Tavallisin substraatti on glukoosi osana glykolyysiä, mutta entsyymi katalysoi fosfaattijohdannaisten muodostumista myös muista heksooseista, kuten mannoosista ja fruktoosista. Heksokinaasin EC-numero on EC 2.7.1.1. WebHexokinase is responsible for glucose phosphorylation, a process fundamental to regulating glucose uptake. In some tissues, hexokinase translocates to the mitochondria, thereby increasing its efficiency and decreasing its susceptibility to product inhibition. It may also decrease free radical formation in the mitochondria and prevent apoptosis.

Generally, hexokinase-2 is bound to the VDAC-1 and maintains the integrity of outer membrane of mitochondria. Given the effects of dioscin on hexokinase-2 expression, we speculated that the interaction between hexokinase-2 and VDAC-1 would be affected by dioscin. ...
WebHK2. Hexokinase 2 also known as HK2 is an enzyme which in humans is encoded by the HK2 gene on chromosome 2. [5] [6] Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes hexokinase 2, the predominant form found in skeletal muscle.
