The site of inhibition of blood clotting by soy bean trypsin inhibitor.
a cofactor which accelerates the rate of of the enzyme-substrate complex (2). A trypsin inhibitor, isolated from so Kunitz (3), is also capable of delaying t' tion of blood. Previous studies by six investigators have shown that it inhibi phase of coagulation and has no effect tivity of thrombin (4-10). None of ti of workers, however, was able to ascerta the soy bean trypsin inhibitor (SBTI) wit...
متن کاملEffect of Blood Thrombokinase, as Influenced by Soy Bean Trypsin Inhibitor; Ultracentrifugation, and Accessory Factors
1. Crystallized soy bean trypsin inhibitor, at a concentration of 100 microg./ml., suppressed the production of thrombin from a mixture of prothrombin and blood thrombokinase. The experiment was performed in the presence of 0.011 M oxalate, in order to minimize the possibility of participation by accessory factors which require ionic calcium. The results are in accord with the view that thrombo...
متن کاملTrypsin inhibitor activity in the field bean (Vicia faba L.).
Wilson and McNab' reported an increase in live-weight and a reduction in pancreas size of chicks when field beans (Viciu fabu L.) were autoclaved at 120 "C for 30 min. Such effects may be due to the presence in the raw field bean of a trypsin inhibitor analogous to those found in the soyabean and other legumes. Information on the presence of trypsin inhibitors in the field bean and on growth of...
متن کاملFluorescence polarization decay of tyrosine in lima bean trypsin inhibitor.
The fluorescence of lima bean trypsin inhibitor is due to a single tyrosine residue at position 69. The lifetime of this tyrosine fluorescence is 620 +/- 50 ps (mean +/- SD) and is little affected by addition of 0.88 M citrate, an efficient quencher of tyrosine fluorescence. The steady-state emission intensity is also only weakly reduced by the quencher. The tyrosine is thus not accessible to t...
