Plant Proteomic of Post-Translational Modifications

Post-translational modifications (PTMs) refer to the covalent processing of post-translational proteins. By adding a modification group to one or more amino acid residues, it can change the physical and chemical properties of the protein, which in turn affects the spatial conformation and activity state, subcellular localization, folding and its stability as well as protein-protein interactions, affecting almost all aspects of normal cell biology.

What We Offer

• Phosphorylated plant proteome analysis
• Acetylated plant proteome analysis
• Ubiquitinated plant proteome
• Glycosylated plant proteome
• Methylated plant proteome
• Identification of disulfide bonds in plant proteins
• Histone post-translational modifications
• Detection of SUMOylation in plant proteins

Since post-translational modified proteins are low in the sample and have a wide dynamic range, they must be enriched before identification. Besides, the stability of the modifications and the detection efficiency of mass spectrometry are key factors in the analysis of PTMs. Lifeasible has built an advanced analytical platform to characterize PTMs within various plant proteins, and the protein modifications that have been studied at scale are mainly methylation, phosphorylation, acetylation, glycosylation, ubiquitination, etc.
