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

The cDNA clone of Geotrichum candidum (Geo.) lipase was isolated from the Geo. cDNA library by colony hybridization using 32P-labeled oligonucleotides corresponding to a partial amino acid sequence of this enzyme. The nucleotide sequence of the cDNA determined by the

Coeliac disease (CD) is an enteropathy caused by an immune reaction towards wheat gluten and similar proteins from barley and rye. It was shown that some gluten peptides spontaneously form N-terminal L-pyroglutamate. This modification could potentially make gluten more resistant

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

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
