背景 | Marapsin, pancreasin, and channel-activating protease 2 (CAP-2) are different names for the same serine protease that is expressed strongly in the pancreas (1, 2). The protein is synthesized with a signal peptide (amino acid residues 1‑22), a pro peptide (residues 23‑34) and a mature chain (residues 35‑290) corresponding to the serine protease domain. The full-length protein was expressed and the secreted protein purified. The N-terminal sequencing results indicate that the purified protein is a disulfide bond-linked dimer formed between the pro peptide and the mature chain. The active enzyme has low activity against peptide substrates tested, but high activity against thioester substrates. The peptidase activity is inhibited by 20 mM benzamidine. |
