The ‘allosteron’ model for entropic allostery of self-assembly (2018)
Journal Article
McLeish, T., Schaefer, C., & von der Heydt, A. (2018). The ‘allosteron’ model for entropic allostery of self-assembly. Philosophical Transactions of the Royal Society B: Biological Sciences, 373(1749), Article 20170186. https://doi.org/10.1098/rstb.2017.0186

Using the simple ‘allosteron’ model, we show that it is possible, in principle, to elicit pathways by which fluctuation allostery affects self-assembly of protein complexes. We treat the cases of (i) protein fibrils and nucleation, (ii) n-mer protein... Read More about The ‘allosteron’ model for entropic allostery of self-assembly.

We study the phenomenon of migration of the small molecular weight component of a binary polymer mixture to the free surface using mean field and self-consistent field theories. By proposing a free energy functional that incorporates polymer-matrix e... Read More about Elasticity dominated surface segregation of small molecules in polymer mixtures.

We examine the analogy between evolutionary dynamics and statistical mechanics to include the fundamental question of ergodicity—the representative exploration of the space of possible states (in the case of evolution this is genome space). Several p... Read More about Are there ergodic limits to evolution? Ergodic exploration of genome space and convergence.

Dynamic Transmission of Protein Allostery without Structural Change: Spatial Pathways or Global Modes? (2015)

We examine the contrast between mechanisms for allosteric signaling that involve structural change, and those that do not, from the perspective of allosteric pathways. In particular we treat in detail the case of fluctuation-allostery by which amplit...
