The generation of novel subsets of phosphorylation sites is needed to complement the present Arabidopsis plasma membrane phosphoprotein repertoire, where several families of proteins are under-represented. In this work, different combinations of chromatographic steps were first compared for capacity to resolve model phosphopeptides before characterisation from PSD fragments in MALDI MS/MS. Nearly half of the phosphorylation sites detected in the Arabidopsis plasmalemma using the optimised… CONTINUE READING
