Biochemical Activity (Proteolytic Processing)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Structural change in alpha-chymotrypsin induced by complexation with alpha 1-antichymotrypsin as seen by enhanced sensitivity to proteolysis.

Stavridi ES, O'Malley K, Lukacs CM, Moore WT, Lambris JD, Christianson DW, Rubin H, Cooperman BS

Both human neutrophil elastase (HNE) and free chymotrypsin (Chtr) proteolyze Chtr within the complex that Chtr forms with antichymotrypsin (ACT). As free Chtr is stable both to self-digestion and to digestion by HNE, these results are indicative of a stability and/or conformational change in Chtr that accompanies complex formation. As determined by both N-terminal sequence analysis and matrix-assisted laser desorption ... [more]
