Thomson2009 – Unlimited multistability in multisite phosphorylation systems

ABSTRACT: This model describes a distributive, sequential system with n = 4, which is a simplified example of unlimited multistability in multisite phosphorylation systems. This method can be applied to systems with multiple substrates and enzymes. This model is described in the article: Unlimited multistability in multisite phosphorylation systems. Thomson, Matthew & Gunawardena, Jeremy. (2009). Nature. 460. 274-7. 10.1038/nature08102 (https://www.nature.com/articles/nature08102). Antimony and Tellurium used. Figure 2 of the reference publication has been reproduced. The code files are available on Github (https://github.com/SunnyXu/Unlimited_multistability). The simulation was performed using Spyder for Tellurium 3.7 (http://tellurium.analogmachine.org/).

Reversible phosphorylation on serine, threonine and tyrosine is the most widely studied posttranslational modification of proteins. The number of phosphorylated sites on a protein (n) shows a significant increase from prokaryotes, with n </= 7 sites, to eukaryotes, with examples having n >/= 150 sites. Multisite phosphorylation has many roles and site conservation indicates that increasing numbers of sites cannot be due merely to promiscuous phosphorylation. A substrate with n sites has an expon ...[more]

Project description:Markevich2004 - MAPK double phosphorylation, ordered Michaelis-Menton The model corresponds to the schemas 1 and 2 of Markevich et al 2004, as described in the figure 1 and modelled using Michaelis-Menten like kinetics. Phosphorylations and dephosphorylations follow distributive ordered kinetics. It reproduces figure 3 of the main article. This model is described in the article: Signaling switches and bistability arising from multisite phosphorylation in protein kinase cascades. Markevich NI, Hoek JB, Kholodenko BN. J. Cell Biol. 2004 Feb; 164(3): 353-359 Abstract: Mitogen-activated protein kinase (MAPK) cascades can operate as bistable switches residing in either of two different stable states. MAPK cascades are often embedded in positive feedback loops, which are considered to be a prerequisite for bistable behavior. Here we demonstrate that in the absence of any imposed feedback regulation, bistability and hysteresis can arise solely from a distributive kinetic mechanism of the two-site MAPK phosphorylation and dephosphorylation. Importantly, the reported kinetic properties of the kinase (MEK) and phosphatase (MKP3) of extracellular signal-regulated kinase (ERK) fulfill the essential requirements for generating a bistable switch at a single MAPK cascade level. Likewise, a cycle where multisite phosphorylations are performed by different kinases, but dephosphorylation reactions are catalyzed by the same phosphatase, can also exhibit bistability and hysteresis. Hence, bistability induced by multisite covalent modification may be a widespread mechanism of the control of protein activity.

Project description:The model corresponds to the schema 3 of Markevich et al 2004, as described in the figure 2 and the supplementary table S2. Phosphorylations follow distributive random kinetics, while dephosphorylations follow an ordered mechanism. The phosphorylations are modeled with three elementary reactions: E+SES->E+P The dephosphorylations are modeled with five elementary reactions: E+SES->EPE+P The model reproduces figure 5 in the main article.

Project description:The model describes the double phosphorylation of MAP kinase by an ordered mechanism using the Michaelis-Menten formalism. Two different enzymes, MAPKK1 and MAPKK2, successively phosphorylate the MAP kinase, but one and the same phosphatase dephosphorylates both sites. The model reproduces figure S9 in the supplemental material of the article.
