Allosteric post-translational modification codes.
Post-translational modifications (PTMs) have been recognized to impact protein function in two ways: (i) orthosterically, via direct recognition by protein domains or through interference with binding; and (ii) allosterically, via conformational changes induced at the functional sites. Because different chemical types of PTMs elicit different structural alterations, the effects of combinatorial...
متن کاملMethylglyoxal modification of protein. Chemical and immunochemical characterization of methylglyoxal-arginine adducts.
Methylglyoxal (MG), an endogenous metabolite that increases in diabetes and is a common intermediate in the Maillard reaction (glycation), reacts with proteins and forms advanced glycation end products. In the present study, we identify a novel MG-arginine adduct and also characterize the structure of a major fluorescent adduct. In addition, we describe the immunochemical study on the MG-argini...
متن کاملPost-translational modification by SUMO.
Post-translational modifications (PTMs) are chemical alterations to a protein following translation, regulating stability and function. Reversible phosphorylation is an example of an important and well studied PTM involved in a number of cellular processes. SUMOylation is another PTM known to modify a large number of proteins and plays a role in various cellular processes including: cell cycle ...
متن کاملGlobal Post-Translational Modification Discovery
A new global post-translational modification (PTM) discovery strategy, G-PTM-D, is described. A proteomics database containing UniProt-curated PTM information is supplemented with potential new modification types and sites discovered from a first-round search of mass spectrometry data with ultrawide precursor mass tolerance. A second-round search employing the supplemented database conducted wi...
متن کاملPost-Translational Modification on Arginine and Function of CCAAT/Enhancer Binding Protei α
The transcription factor CCAAT/enhancer-binding protein α (C/EBPα) coordinates cell cycle arrest and terminal differentiation of neutrophil granulocytes and adipocytes. Mutations in C/EBPα are frequently associated with acute myeloid leukemia. Mass spectrometric analysis revealed that citrullination occurred on multiple conserved C/EBPα arginine residues including R297 in the C/EBPα basic regio...
