definizione di 헥소키나아제 nel dizionario coreano
esochinasi È un enzima che catalizza la reazione del corrispondente esoso-6-fosfato trasferendo il gruppo fosfato dall'ATP al glucosio o ad altri esosi ed è distribuito in batteri, lieviti, animali e piante. L'esochinasi nel lievito è cristallizzata e ha un peso molecolare di circa 96000. Negli animali sono stati trovati vari enzimi omozigoti in esochinasi. 헥소키나아제
포도당이나 그 밖의 헥소스에 ATP로부터 인산기를 전이하여 대응하는 헥소스-6-인산의 생성반응을 촉매하는 효소로 세균·효모·동물·식물체에 분포한다. 효모의 헥소키나아제는 결정화되어 있고, 분자량이 약 9만 6000인 단백질이고 동물에서는 헥소키나아제에 각종 동질효소가 발견되었다.

Glucose Metabolism in the Brain - 7페이지
If glycolysis were not regulated, metabolism of all available glucose that entered the brain would simply consume glucose and ATP, trap phosphate as triose-P, and produce lactate. Major sites for control of glycolytic flux are hexokinase, ...

These agents included not only G-6-P and the amphipathic compound, clotrimazole, but also the N-terminal oligopeptide of hexokinase II. This implies that the inhibitory effect of hexokinase II was not due solely to the occupation of the site that ...

Hexokinase/Glucokinase. Hexokinase, which is found in most tissues except liver and pancreas, has a low Km (0.10 mM) for glucose compared to the blood glucose concentration of 5 mM. It is strongly inhibited by the product of its reaction, ...

The reason is that the next reaction in the glycolytic pathway after hexokinase is the freely reversible iso- merization of glucose-6-phosphate to fructose-6-phosphate, in effect, a rearrangement of the carbonyl group from C-l to C-2.
