phosphorylase kinase b-subunit fragment 420-436

Phosphorylase Kinase β-Subunit Fragment (420-436) is a peptide fragment (430-436) derived from the β-Subunit of phosphorylase kinase. Phosphorylase kinase, a serine threonine-specific protein kinase, plays a crucial role in the activation of glycogen phosphorylase for the release of glucose-1-phosphate from glycogen[1].

P34cdc2 Kinase Fragment，与酵母有丝分裂中DNA复制的完整度相关，并能磷酸化丝裂原激活蛋白MAP2，进而调节爪蟾卵母细胞减数分裂中的微管聚合活性。

This Mitogen-activated protein kinase (MAP kinase) fragment has a peptide sequence of Lys-Tyr-Ile-His-Ser-Ala-Asn-Val-Leu. The MAP kinases are serine threonine-specific protein kinases belonging to the CMGC (CDK MAPK GSK3 CLK) kinase group.

Thrombin is a trypsin-like serine protease that is encoded by the F2 gene in humans. Thrombin is produced by the enzymatic cleavage of two sites on prothrombin by activated Factor X (Xa). Thrombin in turn acts as a serine protease that converts soluble
