AKR1B1 蛋白, Human (His)

The AKR1B1 protein uses NADPH to reduce various carbonyl compounds to alcohols. AKR1B1 Protein, Human (His) is the recombinant human-derived AKR1B1 protein, expressed by E. coli , with N-His, N-10*His labeled tag. The total length of AKR1B1 Protein, Human (His) is 316 a.a., with molecular weight of ~36 kDa.

AKR1B1 是一种多功能酶，可催化多种含羰基化合物依赖 NADPH 还原为其各自的醇。它对内源代谢物表现出酶活性，包括芳香族和脂肪族醛、酮、单糖、胆汁酸和异生物质底物。作为多元醇途径中的关键酶，AKR1B1 通过催化葡萄糖还原为山梨醇，在高血糖中发挥着关键作用。该酶还可以减少类固醇及其衍生物、前列腺素，并对视网膜表现出低活性。此外，AKR1B1 还参与膳食和脂质衍生的不饱和羰基化合物的解毒，例如巴豆醛、4-羟基壬烯醛、反式-2-己烯醛、反式-2,4-己二醛及其谷胱甘肽缀合羰基化合物 (GS-羰基化合物) 。值得注意的是，它催化磷脂酰胆碱和磷脂酰乙醇酰胺氧化产生的各种磷脂醛的还原，进一步强调了其广泛的底物特异性及其在细胞解毒过程中的不可或缺的作用。

Measured by its ability to catalyzes glucuronic acid decomposition in the presence of NADPH. The specific activity is 132.9 U/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
