ProteomicsImpact of bioinformatic search parameters for peptide identification and their post-translational modifications: case study of proteolyzed gelatines from beef, pork and fish.
Bioinformatic software allowing the identification of peptides by confrontation of peptide fragmentation spectra obtained by mass spectrometry against targeted databases or directly by de novo sequencing are now mandatory in peptidomics/proteomics approach. The programming of the identification soft...

ProteomicsCasein phoshopeptides identification by partial-, double-dephosphorylation and endoGluC digestion
The aim of the present study was the development of a relatively simple method without enrichment step to detect, in a mixture of peptides and phosphopeptides, a maximum of CPPs, including multi-phosphorylated and large-size CPPs, by using high pressure liquid chromatography (HPLC), high-resolution ...

ProteomicsProteomics and bioinformatics guided discovery of microalgal multifunctional peptides for novel nutraceutical applications
This study aimed to identify and characterize bioactive peptides derived from protein hydrolysates of Arthrospira platensis (APPH) and Tetraselmis chuii (TCPH) using an integrated peptidomics and bioinformatics approach. Proteins extracted from the microalgae were hydrolyzed using pepsin (EC 3.4.23....
