General description

Endoproteinase Asp-N is a metallo endoprotease. It is obtained from a mutant strain of Pseudomonas fragi, which hydrolyzes peptide bonds on the N-terminal side of aspartic and cysteic acid residues. Asp-N is used in proteomics for peptide mapping and protein sequence work due to its highly specific cleavage of peptides.

Application

Endoproteinase Asp-N from Pseudomonas fragi mutant strain has been used for the digestion of specific proteins to prepare peptides and for the analysis of generated peptides by MS (mass spectrometry) method.
