Realistic enzymology for post-translational modification: zero-order ultrasensitivity revisited.
Unlimited ultrasensitivity in a kinase/phosphatase "futile cycle" has been a paradigmatic example of collective behaviour in multi-enzyme systems. However, its analysis has relied on the Michaelis-Menten reaction mechanism, which remains widely used despite a century of new knowledge. Modifying and demodifying enzymes accomplish different biochemical tasks; the donor that contributes the modify...
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 کاملComputational Prediction of Post-Translational Modification Sites in Proteins
The last several decades have witnessed rapid progresses in identification and functional analysis of post-translational modifications (PTMs) in proteins. Through temporal and spatial modification of proteins by covalent attachment of additional chemical groups and other small proteins, proteolytic cleavage or intein splicing, PTMs greatly expand the proteome diversity and play important roles ...
متن کاملPost-translational modification of PII signal transduction proteins
The PII proteins constitute one of the most widely distributed families of signal transduction proteins in nature. They are pivotal players in the control of nitrogen metabolism in bacteria and archaea, and are also found in the plastids of plants. Quite remarkably PII proteins control the activities of a diverse range of enzymes, transcription factors and membrane transport proteins, and in al...
متن کاملPost-translational modification and folding of secreted proteins.
The production of a functional protein does not end with the termination of the growing polypeptide chain. This, while clearly true of all proteins, is particularly obvious in the case of secretory proteins. While all proteins must fold to a functional conformation, and many must assemble into some supramolecular structure, secretory proteins must also make their way across membranes and throug...
