Abstract
The determination of protein structure and protein-protein interactions using homobifunctional crosslinking reagents with normal and N-15 labeled proteins was discussed. Recombinant CMP-NeuAc synthetase and HIV-integrase were prepared from normal and N-15 enriched media. In the case of crosslinked peptides originating from protein-protein interactions, some gain was obtained from a pattern recognition point of view, since these peptide types were observed as quartets. The identification of crosslinked peptides was confirmed by electrospray ionization (ESI)-mass spectrometry (MS)/MS using a quadrupole time-of-flight (TOF) instrument or MALDI-PSD.
