Phosphorylation is a key process for changing the activity and function of proteins. The impact of phospho-serine (pSer), -threonine (pThr) and -tyrosine (pTyr) is certainly understood for some proteins. Recently, peptides and proteins containing N-phosphorylated amino acids such as phosphoarginine (pArg), phosphohistidine (pHis) and phospholysine (pLys)(More)
Protein phosphorylation controls major processes in cells. Although phosphorylation of serine, threonine, and tyrosine and also recently histidine and arginine are well-established, the extent and biological significance of lysine phosphorylation has remained elusive. Research in this area has been particularly limited by the inaccessibility of peptides and(More)
Tandem mass spectrometry (MS/MS) strategies coupled with collision-induced dissociation (CID) or radical-driven fragmentation techniques such as electron-capture dissociation (ECD) or electron-transfer dissociation (ETD) have been successfully used for comprehensive phosphoproteome analysis. However, the unambiguous characterization of the phosphorylation(More)
In contrast to protein O-phosphorylation, studying the function of the less frequent N- and S-phosphorylation events have lagged behind because they have chemical features that prevent their manipulation through standard synthetic and analytical methods. Here we report on the development of a chemoselective synthetic method to phosphorylate Cys side-chains(More)
