Looking at structure, stability, and evolution of proteins through the principal eigenvector of contact matrices and hydrophobicity profiles
Ugo Bastolla, Markus Porto, H. Eduardo Roman +1
We review and further develop an analytical model that describes how thermodynamic constraints on the stability of the native state influence protein evolution in a site-specific m…
Prediction of site-specific amino acid distributions and limits of divergent evolutionary changes in protein sequences
Markus Porto, H. Eduardo Roman, Michele Vendruscolo +1
We derive an analytic expression for site-specific stationary distributions of amino acids from the Structurally Constrained Neutral (SCN) model of protein evolution with conservat…
The principal eigenvector of contact matrices and hydrophobicity profiles in proteins
Ugo Bastolla, Markus Porto, H. Eduardo Roman +1
With the aim to study the relationship between protein sequences and their native structures, we adopt vectorial representations for both sequence and structure. The structural rep…
Statistical properties of neutral evolution
Ugo Bastolla, Markus Porto, H. Eduardo Roman +1
Neutral evolution is the simplest model of molecular evolution and thus it is most amenable to a comprehensive theoretical investigation. In this paper, we characterize the statist…
A pure-carbon ring transistor: The role of topology and structure
G. Cuniberti, J. Yi, M. Porto
We report results on the rectification properties of a carbon nanotube (CNT) ring transistor, contacted by CNT leads, whose novel features have been recently communicated by Watana…
Connectivity of neutral networks and structural conservation in protein evolution
Ugo Bastolla, Markus Porto, H. Eduardo Roman +1
Protein structures are much more conserved than sequences during evolution. Based on this observation, we investigate the consequences of structural conservation on protein evoluti…
