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

An experimental approach using SDS-PAGE, in-gel trypsin digestion and proteomic analysis identified five endosomal proteins. Trypsin cleavage of the high-risk HPV-16 E5 protein (16E5) generates a unique four-amino acid C-terminal peptide that serves as a marker for E5 expression in transfected cells and epithelial cell lines containing integrated and episomal HPV-16 DNA.

Unit Definition

One unit will hydrolyze 1.0 μmole of BAEE per min at pH 8.0 at 30 °C (titrimetric assay).

Physical form

Suspension in approx. 10 mM acetic acid, pH 3.2, containing preservative

Botulinum neurotoxin serotypes A and B (BoNT/A & B) are highly effective medicines to treat hyperactive cholinergic neurons. Due to neutralizing antibody formation, some patients may become non-responders. In these cases, the serotypes BoNT/C-G might become treatment alternatives. BoNT/D is

It is well known that the activation of mast cells due to the binding of mastoparan to the G(α) subunit of trimeric G proteins involves exocytosis regulation. However, experimental evidence in the literature indicates that mastoparan can also activate certain
