一般描述

磷酸化酶激酶包含四个亚基,每个亚基含有α、β、γ以及sigma成分。该sigma成分结合4个钙分子,称为钙调蛋白,而其γ单位可用作催化亚基。

应用

来自兔肌肉的磷酸化酶激酶已应用于一项研究,以评估糖原磷酸化酶的特征。 此外,它还应用于研究肌动蛋白对不同形式肌磷酸化酶激酶的活化作用。

单位定义

在30°C、pH 7.7和ATP存在的条件下,一个单位每分钟可将磷酸化酶B转化为1.0 μ摩尔磷酸化酶。

外形

含有(NH42SO4、蔗糖、β-甘油磷酸盐和二硫赤藓糖醇的冻干粉

Angiogenesis is essential for development and tumor progression. With the aim of identifying new compound inhibitors of the angiogenesis process, we used an established enhanced green fluorescent protein-transgenic zebrafish line to develop an automated assay that enables high-throughput screening of
