Fig. 1 Pedigree of a family with chronic pancreatitis and D22G mutation of the cationic trypsinogen. The patients with documented chronic pancreatitis are represented by closed symbols; individuals with suspected disease are depicted in grey. *D22G variant present.

Fig. 2 HPLC separation of oligopeptide digests. (A) Wild-type peptide (pWT), no trypsin; (B) pWT, 30 minutes of trypsin; (C) pD22G, 30 minutes of trypsin; (D) pK23R, 30 minutes of trypsin. Arrows indicate the position of the octapeptide. Gastroenterology , DOI: ( /gast ) Copyright © 2000 American Gastroenterological Association Terms and Conditions

Fig. 3 pH-dependent hydrolysis of synthetic peptides by trypsin. Wild-type (pWT) and mutant (pD22G, pK23R) peptides were incubated with or without trypsin for 30 minutes. After chromatographic separation of the hydrolytic products, the percentage of peptide digestion was measured by integration of the areas under the respective peaks. Values are means ± SE; n = 4; *P < 0.05. Gastroenterology , DOI: ( /gast ) Copyright © 2000 American Gastroenterological Association Terms and Conditions
