- 活力定义:One unit will convert one micromole of D-Hexose to D-Hexose-6-phosphate per minute at pH 8.0 at 30℃.
- 分子量:55kDa (SDS-PAGE)
- 等电点:5.5。
- 最适pH:9.0。
- 最佳温度:50℃~55℃。
- 性状:白色粉末。
- 来源:酿酒酵母提取。
- 储存条件: -20℃
- 用途: 为催化己糖6位上由ATP使之产生磷酸化反应的酶。对α-D葡萄糖的亲和性很高(Km=1×10-5M),对其他的己糖也可进行磷酸化。此反应的平衡向右偏移。△G°’=4.0千卡。该酶可被Mg2 、 K 所活化,但可被HS试剂阻抑。
- 敏感性: 易潮湿
