ANALYSIS OF NON-ENZYMATIC POSTTRANSLATIONAL MODIFICATED (GLYCATED) ALBUMIN BY NANO-LC/MS/MS

Popis výsledku v původním jazyce

Posttranslational modifications of proteins are important reactions, which significantly affect the function of proteins in the organism. In principle, they can be divided into enzymatic and non-enzymatic modifications. Non-enzymatic reactions include glycation (earlier called nonezymatic glycosylation), which plays an important role in the development of chronic complications of diabetes mellitus, uremia, in the process of aging and degeneration of the brain.This work deals with the study of glycated albumins (human serum albumin and bovine serum albumin). Methodologically we used nano-liquid chromatography coupled to Q-TOF mass spectrometer. In vitro modified proteins were cleavaged by trypsin and arising peptides were separated on C18 nano column with trap-column. Peptides and their modifications were analysed by high-resolution Q-TOF mass spectrometer MaXis with precision determination of mass below 2 ppm. We found some modifications of proteins. Besides well known carboxymethyllys
