己糖激酶
英文名稱(chēng):HK;Hexokinase from Saccharomyces cerevisiae;ATP:D-Hexose-6-phosphotransferase;Hexokinase fromyeast
其他名稱(chēng):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-glucoseper 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):Hexokinaserequires Mg2+ ions (KM = 2.6 mM) for activity. Hexokinase is activated bycatecholamines 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?!?/span>G°’=4.0千卡。該酶可被Mg2 、 K 所活化,但可被HS試劑阻抑。
保存:-20℃
