Comparison of proteolysis in native, heat-treated and aged proteins from turkey meat.
1. The present study compared the ability of native, heat-treated and aged turkey breast muscle proteins to undergo proteolysis by digestive tract proteases. 2. Domestic turkey toms were slaughtered under laboratory conditions. Breast muscles were excised immediately post mortem; one was placed under conditions to develop exudative meat by maintaining the muscle at 40 degrees C for at least 30 ...
متن کاملProduct Inhibition in Native-State Proteolysis
The proteolysis kinetics of intact proteins by nonspecific proteases provides valuable information on transient partial unfolding of proteins under native conditions. Native-state proteolysis is an approach to utilize the proteolysis kinetics to assess the energetics of partial unfolding in a quantitative manner. In native-state proteolysis, folded proteins are incubated with nonspecific protea...
متن کاملLimited in vivo proteolysis of aggregated proteins.
Degradation pathways of insoluble proteins have been analyzed in Escherichia coli by using a N-terminal beta-galactosidase fusion protein (VP1LAC) that aggregates immediately after its synthesis. In recombinant E. coli cells, lower molecular mass products, antigenically related to the entire fusion, accumulate together with the entire fusion. In absence of protein synthesis, the insoluble intac...
متن کاملThe products of proteolysis of some purified proteins.
Recent studies on the digestion of proteins by the proteolytic enzymes of the gastrointestinal tract have resulted in a considerable revision of our concepts on how these enzymes act. Tiselius and Eriksson-Quensel (1) studied the mechanism of the peptic digestion of crystalline egg albumin by electrophoretic examination of the products of proteolysis. They observed that, as digestion proceeded,...
متن کاملCell cycle-regulated proteolysis of mitotic target proteins.
The ubiquitin-dependent proteolysis of mitotic cyclin B, which is catalyzed by the anaphase-promoting complex/cyclosome (APC/C) and ubiquitin-conjugating enzyme H10 (UbcH10), begins around the time of the metaphase-anaphase transition and continues through G1 phase of the next cell cycle. We have used cell-free systems from mammalian somatic cells collected at different cell cycle stages (G0, G...
