Description

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.

Unit Definition

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).

Preparation Note

Prepared by the method of Labouesse, J. and Gervais, M., Eur. J. Biochem., 2, 215 (1967).
