For larger proteins, efficient deblocking prior to Edman sequencing is especially important to obtain quality, extended sequencing data which is limited by the stepwise accumulation of background from the random acid hydrolysis of the protein. Therefore, any portion that remains

Pyrrolidone carboxyl peptidase (EC 3.4.11.8) is an exopeptidase commonly called PYRase, which hydrolytically removes the pGlu-proteins. pGlu also known as pyrrolidone carboxylic acid may occur naturally by an enzymatic procedure or may occur as an artifact in proteins or peptides.

Typically, the removal of pyroglutamate from the protein chains of immunoglobulins with the enzyme pyroglutamate aminopeptidase requires the use of chaotropic and reducing agents, quite often with limited success. This article describes a series of optimization experiments using elevated temperatures

We previously described a proteome-wide, peptide-centric procedure for sorting protein N-terminal peptides and used these peptides as readouts for protease degradome and xenoproteome studies. This procedure is part of a repertoire of gel-free techniques known as COmbined FRActional DIagonal Chromatography
