Title: N-Glycopeptide Profiling in Arabidopsis Inflorescence

Abstract

This study presents the first large scale analysis of plant intact glycopeptides. Using wheat germ agglutinin lectin weak affinity chromatography to enrich modified peptides, followed by ETD fragmentation tandem mass spectrometry, glycan compositions on over 1100 glycopeptides from 270 proteins found in Arabidopsis inflorescence tissue were characterized. While some sites were only detected with a single glycan attached, others displayed up to 16 different glycoforms. Among the identified glycopeptides were four modified in non-consensus glycosylation motifs. Finally, while most of the modified proteins are secreted, membrane, ER or Golgi localized proteins, surprisingly N-linked sugars were detected on a protein predicted to be cytosolic or nuclear.
