Apoptosis

Phosphocreatine di-tris salt is a phosphorylated creatine molecule that serves as a high-energy phosphate reservoir in the muscles of vertebrates and some invertebrates, providing phosphate for the conversion of ADP to ATP.

Cathepsin B from bovine spleen (Cathepsin B) is a member of the cysteine protease papain-like family. Cathepsin B is synthesized as a preproenzyme consisting of 335 amino acids, with a calculated molecular weight of approximately 36.7kDa. Cathepsin B is localized in the endosomal/lysosomal compartment, where Cathepsin B functions as both an endopeptidase and an exopeptidase. Cathepsin B primarily participates in the routine turnover of intracellular and extracellular proteins, thereby maintaining the homeostatic metabolic activity within the cell.
