General description

枯草素 是一种无二硫键的非糖基化单肽链,其分子量为27kda。
该酶在pH 8-10下稳定,可在24小时保存高达90%的活性。其55-60℃下具有最大活性。

Application

该产品已与其他酶一起用于 原位 蛋白水解,以制备适用于结构测定的晶体。它还被用于分离可用于 体外 功能研究的肌膜下(SS)和肌原纤维间(IMF)线粒体。
这是由 衣芽孢杆菌发酵而分离出来的一种蛋白水解酶。这是一种丝氨酸内蛋白酶,对天然和变性蛋白具有广泛的特异性,在碱性条件下具有活性。

Biochem/physiol Actions

枯草素A 是丝氨酸S8内蛋白酶家族的一个成员。它具有广泛的特异性,在P1位置有较大的非荷电残基。它可水解天然和变性蛋白,并且在碱性条件下具有活性。
蛋白酶通过水解肽键分解蛋白质。 蛋白酶可被丝氨酸活性位点抑制剂灭活,如苯基甲基磺酰氟(PMSF)和二异丙基氟磷酸酯。 蛋白酶,P5380的产物,是一种丝氨酸内蛋白酶,对天然和变性蛋白具有广泛的特异性,在碱性条件下具有活性。 它在某些有机溶剂中具有活性,如干辛烷。

Other Notes

一单位在37°C、pH 7.5条件下每分钟可水解1.0μmole(181 μg)的酪氨酸(福林酚试剂显色)。

Peroxisome proliferator-activated receptors (PPARs) alter the expression of genes involved in regulating lipid metabolism. Rosiglitazone, a PPARgamma agonist, induces tissue-specific effects on lipid metabolism; however, its mode of action in skeletal muscle remains unclear. Since fatty acid translocase (FAT/CD36) was

Actin polymerization powers key cellular processes, including motility, morphogenesis, and endocytosis. The actin turnover cycle depends critically on "re-charging" of ADP-actin monomers with ATP, but whether this reaction requires dedicated proteins in cells, and the underlying mechanism, have remained elusive.
