描述

The COLAER_02088 Protein, acting as a 7beta-hydroxysteroid dehydrogenase, transforms 7-oxo-lithocholate into chemopreventive UDCA in the human colon, showcasing its role in bile acid metabolism. This enzyme also exhibits reversible reactions, oxidizing UDCA and utilizing NADPH as its preferred electron acceptor, influencing bile acid dynamics and potential therapeutic applications. COLAER_02088 Protein, Collinsella aerofaciens is the recombinant COLAER_02088 protein, expressed by E. coli , with tag free.

研究背景

COLAER_02088 蛋白被称为 7β-羟基类固醇脱氢酶,作为一种酶,有助于还原 7-氧代-石胆酸盐 (7-氧代-LCA) 的 7-氧代基团,从而产生熊去氧胆酸盐 (UDCA)。鉴于 C.aerofaciens 是一种肠道细菌,这种酶很可能在人类结肠中 UDCA 的形成中发挥作用。UDCA 被认为是一种有益的次级胆汁酸,由于其低疏水性而具有化学预防特性,有助于保护肝细胞和胆管上皮细胞免受脱氧胆酸 (DCA) 等疏水性较高的次级胆汁酸 (DCA) 诱导的坏死和凋亡(可能)。此外,该酶具有催化逆反应的能力,将 UDCA 的 7β-羟基氧化回 7-oxo-LCA。它还对熊去氧胆酸盐的牛磺酸和甘氨酸缀合物表现出一定的活性,尽管程度较小。值得注意的是,COLAER_02088 蛋白专门利用 NADPH/NADP(+) 作为电子受体/供体,因为它对 NADH/NAD(+) 没有活性。此外,当 NADPH 存在时,7β-HSDH 也可以减少脱氢胆酸。最后,它已被证明具有氧化熊胆酸的能力。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
