Example Sentences:

  • (14) In the assay of two soybean trypsin inhibitors, the Kunitz and the Bowman-Birk inhibitors, two procedures were used: the current procedure in which the substrate is added last (the S-last test), after inhibitor is mixed with enzyme, and a new procedure in which the enzyme is added last (the E-last test), after inhibitor is mixed with substrate.

  • (17) The enzyme is strongly inhibited by aprotinin, diisopropylfluorophosphate, antipain, leupeptin, and Kunitz-type soybean trypsin inhibitor, but inhibited only slightly by Bowman-Birk soybean trypsin inhibitor, benzamidine, and alpha 1-antitrypsin.
  • (18) Emma Birks, 36, was a volunteer co-ordinator at a worker's co-operative in Birmingham before deciding to go travelling in south-east Asia.
  • (19) This intracellular protease was inhibited by the soybean-derived Bowman-Birk inhibitor (BBI), chymostatin, and L-1-tosylamido-2-phenylethyl chloromethyl ketone, all of which have anticarcinogenic activity, but was unaffected by soybean trypsin inhibitor, which lacks anticarcinogenic activity.
  • (20) The soybean-derived Bowman-Birk inhibitor (BBI) has been shown to inhibit carcinogenesis in both in vitro and in vivo model systems.
