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.
