PSP 蛋白, Human (His)

PSP protein catalyzes the final irreversible step in carbohydrate biosynthesis of L-serine through dephosphorylation of O-phospho-L-serine. PSP Protein, Human (His) is the recombinant human-derived PSP protein, expressed by E. coli , with C-6*His labeled tag. The total length of PSP Protein, Human (His) is 225 a.a., with molecular weight of 25-30 kDa.

磷酸丝氨酸磷酸酶 (PSP) 负责催化从碳水化合物生物合成 L-丝氨酸的最终不可逆步骤，包括 O-磷酸-L-丝氨酸去磷酸化为 L-丝氨酸。这种酶活性对于各种细胞过程至关重要，因为 L-丝氨酸是蛋白质合成、其他氨基酸生成、核苷酸代谢和谷胱甘肽合成的前体。此外，L-丝氨酸可以发生外消旋作用，形成 D-丝氨酸，起到神经调节剂的作用。PSP 在调节 L-丝氨酸的可用性方面的作用强调了其在多种代谢途径和细胞功能中的重要性。还可能参与 O-磷酸-D-丝氨酸的去磷酸化，尽管这一方面仍有待证实。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
