General description
The trypsin molecule has two domains: one is related to the enzyme active site and the tryptophan residues; the other is related to the 8-anilinonaphthalene-1-sulfonate binding.
Application
Trypsin has been used in a study to assess the ontogeny of the endocrine pancreas in the fetal/newborn baboon. Trypsin digestion and hydrogen/deuterium exchange support the transition between inward- and outward-facing conformations during the catalytic cycle of the bacterial multidrug ATP-binding cassette transporter.
Biochem/physiol Actions
Lys-acetylated trypsin is less susceptible to autolysis than the native form.
Preparation Note
Prepared by the method of Labouesse, J. and Gervais, M., Eur. J. Biochem., 2, 215 (1967).
Other Notes
One BAEE unit will produce a ΔA253 of 0.001 per min at pH 7.6 at 25° C using BAEE as substrate. Reaction volume = 3.2 mL (1 cm light path).
