Birk


Definition:

  • (n.) A small European minnow (Leuciscus phoxinus).

Example Sentences:

  • (1) The inhibitors tested in order of their decreasing effectiveness were alpha-1-proteinase inhibitor (alpha-1-antitrypsin), lima bean trypsin inhibitor, soybean trypsin inhibitor, Bowman-Birk (soybean) inhibitor, Kunitz pancreatic trypsin inhibitor, porcine Kazal inhibitor, and chicken ovomucoid.

  • (3) Fifty-five 7-week-old male mice were randomized into 11 groups and gavaged 5 days per week with purified Bowman-Birk inhibitor, Bowman-Birk inhibitor concentrate, and autoclaved Bowman-Birk inhibitor concentrate.
  • (4) The established sequence showed that RBTI is composed of 4 domains, domains I and III, and domains II and IV being homologous to the first and the second domains of soybean Bowman-Birk inhibitor, respectively, indicating that RBTI has a duplicated structure of the Bowman-Birk type inhibitor.
  • (5) There are regions of high conservation and high divergence within the 5' leader, mature protein and 3' non-coding regions of the Bowman-Birk inhibitors and in the genes which encode them in different members of this family within the Leguminosae.
  • (6) Therefore, R-BIRK functions as a basal-state enzyme and can be stimulated in an insulin-like manner.
  • (7) Inhibitor C-II was found to be homologous with soybean (Glycine max) Bowman-Birk inhibitor and more closely related to an inhibitor from garden beans (Phaseolus vulgaris).
  • (8) The structure determination and refinement are described, and the structure is compared to other structures of Bowman-Birk inhibitors as well as other families of serine protease inhibitors.
  • (9) The three-dimensional structure of the Bowman-Birk type proteinase inhibitor (PI-II) has been determined by x-ray crystallography and refined at 2.5-A resolution.
  • (10) Previous studies have demonstrated that the soybean-derived Bowman-Birk protease inhibitor (BBI) is effective as a cancer chemopreventive agent in several animal model systems.
  • (11) The trypsin-chymotrypsin inhibitors from dog submandibular glands, from soybeans (Bowman-Birk) and from chickpeas show strong interaction with these proteases (Ki = 10(-8) - 10(-9)M).
  • (12) Birke and Sadler (1983) showed that not only perinatal androgens but also progestogens such as medroxyprogesterone acetate (MPA) affect (in this case: demasculinize) the play behavior of both sexes in the rat.
  • (13) The effect of pH and temperature on the apparent association equilibrium constant (Ka) for the binding of the soybean Bowman-Birk proteinase inhibitor (BBI) and of its chymotrypsin and trypsin inhibiting fragments (F-C(p), F-T(p) and F-T(t), respectively) to bovine alpha-chymotrypsin (alpha-chymotrypsin) and bovine beta-trypsin (beta-trypsin) has been investigated.
  • (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.
  • (15) The results for the total-body-irradiated mice receiving Bowman-Birk inhibitor concentrate suggested an effect midway between these two groups.
  • (16) ATI is the first Bowman-Birk inhibitor that has been found in leaves and is the only member of this family known to be regulated by wounding.
  • (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.

Firk


Definition:

  • (v. t.) To beat; to strike; to chastise.
