Ubiquitin is a small (8.6 kDa) regulatory protein and ubiquitination is an important post-translational modification, in which ubiquitins are attached to a substrate protein. This process contains three main steps: activation, conjugation, and ligation and requires three types of enzymes: ubiquitin-activating enzymes (E1s), ubiquitin-conjugating enzymes (E2s), and ubiquitin ligases (E3s). ubiquitin protein sequence https://www.creative-proteomics.com/services/ubiquitination-2.htm

S-Nitrosylation refers to a covalent attachment of an NO moiety to sulfhydryl residues of proteins. The sulfhydryl residues belongs to a subset of specific cysteine residues in proteins, the resulting SNO is an S-nitrosoprotein. SNOs have a short half-life in the cytoplasm because of the host of reducing enzymes, including glutathione (GSH) and thioredoxin, that denitrosylate proteins. nitrosylation https://www.creative-proteomics.com/services/s-nitrosylation.htm

In top-down proteomics, intact protein molecular ions generated by ESI or MALDI are introduced into mass analyzer and are subjected to gas-phase fragmentation. Top-down analysis facilitates direct observation of C- and N-termini for identification of truncations and distinguish one isoform from the other by different sequences. top-down sequencing https://www.creative-proteomics.com/services/top-down-based-sequencing.htm

The application of Bottom-Up strategy is limited by incomplete or ambiguous characterization of alternative splice forms, diverse modifications and endogenous protein cleavages. As an alternative, the Top-Down strategy has been utilized more with the advancement of analytical instruments. Except for FT-ICR mass spectrometer, invention and innovation of orbitrap mass spectrometer has promote the development of top-down proteomics.
