Działania biochem./fizjol.
A 58-residue protein whose binding to various serine proteases has been extensively studied. It is highly homologous to a family of mamba snake dendrotoxin proteins that inhibit various K+ channels. It also binds to an intracellular site associated with the large conductance Ca2+-activated K+ channel..
Definicja jednostki
One trypsin unit will produce a ΔA253 of 0.001 per min with BAEE as substrate at pH 7.6 at 25 °C; reaction volume 3.2 ml, 1 cm light path.
Uwaga dotycząca przygotowania
Prepared by method of Kunitz and Northrup, J. Gen. Physiol., 19, 991 (1936).
Komentarz do analizy
One mg of trypsin inhibitor will inhibit greater than 1.5 mg of trypsin with activity of approximately 10,000 BAEE units per mg protein.
Protein determined by biuret.

PeaT1 is a proteinaceous elicitor from fungal pathogen Alternaria tenuissima. Our previous research revealed that this elicitor could induce defense response and enhance disease resistance in various plants including Nicotiana plants. However, immune activation mechanisms whereby PeaT1 elicits defense response

Human mesotrypsin is highly homologous to other mammalian trypsins, and yet it is functionally unique in possessing resistance to inhibition by canonical serine protease inhibitors and in cleaving these inhibitors as preferred substrates. Arg-193 and Ser-39 have been identified as

Ghrelin, the only known orexigenic gut hormone produced primarily in the stomach, has lately gained attention as a potential treatment of anorexia and cachexia. However, its biologic stability is highly limited; therefore, a number of both peptide and nonpeptide ghrelin

Serum proteins [molecular weight (MW) > 10,000] are essential for increased insulin-stimulated glucose transport after in vitro muscle contractions. We investigated the role of the kallikrein-kininogen system, including bradykinin, which is derived from kallikrein (MW > 10,000)-catalyzed degradation of serum
