英文名稱：HK；Hexokinase from Saccharomyces cerevisiae；ATP:D-Hexose-6-phosphotransferase；Hexokinase from yeast 
其他名稱：己糖磷酸激酶
CAS號(hào)：9001-51-8

級(jí)別：BR

分子量：~ 54 kDa (monomer)；~110 kDa (dimer)
活力：~ 500 units/mg protein

活力定義：One unit will phosphorylate 1.0 μmole of D-glucose per min at pH 7.6 at 25℃ 
Optimal pH：7.5～9.0

性狀(以下信息僅供參考)：白色粉末。釀酒酵母提取。催化劑（Activators）：Hexokinase requires Mg2+ ions (KM = 2.6 mM) for activity. Hexokinase is activated by catecholamines and related compounds；抑制劑（Inhibitors）：sorbose-1-phosphate, polyphosphates, 6-deoxy-6-fluoroglucose, 2-C-hydroxy-methylglucose, xylose, lyxose, and thiol reactive compounds (Hg2+ and 4-chloromercuribenzoate)
用途：本品僅供科研，不得用于其它用途。(以下用途僅供參考)為催化己糖6位上由ATP使之產(chǎn)生磷酸化反應(yīng)的酶。對(duì)α－D葡萄糖的親和性很高（Km=1×10－5M），對(duì)其他的己糖也可進(jìn)行磷酸化。此反應(yīng)的平衡向右偏移?！鱃°’=4.0千卡。該酶可被Mg2 、K 所活化，但可被HS試劑阻抑。
保存：-20℃
