N-Terminal isotope tagging (NIT) is an important proteomic tool for quantifying proteins in complex mixtures. Here we describe a modified version of the isotope-coded propionylation procedure of Zhang et al. [Zhang et al., Rapid Commun. Mass Spectom. 16 (2002) 2325]

Electron transfer dissociation (ETD) has attracted increasing interest due to its complementarity to collision-induced dissociation (CID). ETD allows the direct localization of labile post-translational modifications, which is of main interest in proteomics where differences and similarities between ETD and CID

In eukaryotic cells, posttranslational modifications (PTMs) on histones regulate chromatin structure and thus impact nearly all chromatin-templated events, including replication, transcription, and DNA repair. During S phase, newly synthesized histones are deposited onto DNA, leading to dilution of total chromatin-associated
