Biochem/physiol Actions

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..

Unit Definition

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.

Preparation Note

Prepared by method of Kunitz and Northrup, J. Gen. Physiol., 19, 991 (1936).

Analysis Note

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.

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

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
