Analysis of adaptive walks on NK fitness landscapes with different interaction schemes

Stefan Nowak, Joachim Krug
2015 Journal of Statistical Mechanics: Theory and Experiment  
Our main tool for the analysis are adaptive walks, an idealized dynamics by which the population moves uphill in fitness and terminates at a local fitness maximum.  ...  The focus is on how this scheme influences the overall shape of the landscape.  ...  Acknowledgments We thank Cristian Giardina for pointing us to the literature on reluctant adaptive walks. This work was supported by DFG within SPP 1590 Probabilistic structures in evolution.  ...

Weighted force analysis method for derivation of multidimensional free energy landscapes from adaptively-biased replica simulations [article]

Fabrizio Marinelli, José D. Faraldo-Gómez
2021 bioRxiv   pre-print
AbstractA methodology is proposed for calculating multidimensional free-energy landscapes of molecular systems, based on post-hoc analysis of multiple molecular dynamics trajectories wherein adaptive biases  ...  facilitates calculating accurate multidimensional free-energy landscapes from different trajectories and time-dependent biases, outperforming other post-hoc unbiasing methods.  ...  For similar reasons, it has been not straightforward so far to apply dynamic histogram [31, 32] or transitionbased reweighting analysis [33, 34] in the context of adaptive biases.  ...

Sequence-Based Analysis of Protein Energy Landscapes Reveals Nonuniform Thermal Adaptation within the Proteome

J. Gu, V. J. Hilser
2009 Molecular biology and evolution  
Unexpectedly, however, the analysis shows that protein thermostability is modified to different extents across the proteome and depends on the functional role for which the protein is involved.  ...  According to the current paradigm, the adaptation of an organism for survival at higher or lower temperatures is facilitated by the adaptation of the component proteins.  ...  This score was used as a measure for comparative analysis to identify nonuniform thermostability modulation within the proteomes for thermal adaptation.  ...

Cross-species analysis traces adaptation of Rubisco toward optimality in a low-dimensional landscape

Yonatan Savir, Elad Noor, Ron Milo, Tsvi Tlusty
2010 Proceedings of the National Academy of Sciences of the United States of America  
The analysis presented here suggests that the evolution of Rubisco is confined to an effectively one-dimensional landscape, which is manifested in simple power law correlations between its kinetic parameters  ...  Our analysis indicates that the specificity of Rubisco is not the main determinant of its efficiency but rather the tradeoff between the carboxylation velocity and CO2 affinity.  ...  Adaptation of Rubisco in the 1D landscape is nearly optimal A longstanding question is the optimality of Rubisco to its environment.  ...
