Trypsin Acetylated from bovine pancreas, Type V-S, >=8,500 BAEE units/mg protein (biuret)

Descriptions

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.

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.
