機能記述

Has activity against the synthetic substrates Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec. The single-chain form is more active than the two-chain form against all of these substrates

関連疾患

Pancreatitis, hereditary

A disease characterized by pancreas inflammation, permanent destruction of the pancreatic parenchyma, maldigestion, and severe abdominal pain attacks.

翻訳後修飾

  • Occurs in a single-chain form and a two-chain form, produced by proteolytic cleavage after Arg-122
  • Sulfation at Tyr-154 increases selectivity towards basic versus apolar residues at the P2' position of inhibitors that bind in a substrate-like fashion. Although the increase in selectivity is relatively small, it may facilitate digestion of a broader range of dietary proteins
