In vitro and in vivo degradation of human gastrin by endopeptidase 24.11.

Abstract

The degradation of human unsulfated heptadecapeptide gastrin (G-17) by human kidney endopeptidase 24.11 has been studied in vitro, and some of the products of degradation have been identified in plasma after in vivo infusion of G-17. The enzyme cleaved G-17 at four peptide bonds: Trp4Leu5, Ala11Tyr12, Gly13Trp14, and Asp16Phe17. The cleavage at Gly-Trp was… (More)
