Comparing Voronoi and Laguerre Tessellations in the Protein-Protein Docking Context

Thomas Bourquard, Julie Bernauer, Jérôme Azé, Anne Poupon
2009 2009 Sixth International Symposium on Voronoi Diagrams  
In our work, we have tested two different, but related, formalisms: the Voronoi and Laguerre tessellations. We present here a comparison of these two models in the context of protein-protein docking.  ...  In order to design an accurate and high-throughput prediction method for protein-protein docking, the first step was to model a protein structure using a formalism allowing fast computation, without losing  ...  Next, we compared the differences observed for parameters between non-native and native conformations for Voronoi and Laguerre tessellations.  ...

Voronoi and Voronoi-related tessellations in studies of protein structure and interaction

Anne Poupon
2004 Current Opinion in Structural Biology  
The tessellation invented by Voronoi in 1908, and other tessellations of space derived from it, provide versatile representations of three-dimensional structures.  ...  In recent years, they have been used to investigate a series of issues relating to proteins: atom and residue volumes, packing, folding, interactions and binding.  ...  In the context of protein structure, the Voronoi tessellation was first used by Richards in 1974 [1] to evaluate the volumes of the atoms in a globular protein, defined as the volume of their Voronoi  ...

Recent Progress and Future Directions in Protein-Protein Docking

David Ritchie
2008 Current protein and peptide science  
This article gives an overview of recent progress in protein-protein docking and it identifies several directions for future research.  ...  Recent results from the CAPRI blind docking experiments show that docking algorithms are steadily improving in both reliability and accuracy.  ...  [159] used a Voronoi tesselation representation of protein shape and a SVM-based machine learning approach to re-score successfully HADDOCK predictions for 4 out of 5 CAPRI targets.  ...

2015 Journal of Molecular Biology  
in the Rosetta and I-Tasser protein decoy sets.  ...  The relative distance and orientation in contacting residue pairs plays a significant role in protein folding and stabilization.  ...  An alternative definition of contacts is based on geometric models such as Voronoi diagram [16, 17] , Laguerre tessellation [18] , Delaunay triangulation [19, 20] , or alpha shape [21, 22] .  ...

New insights into structure and function of bis-phosphinic acid derivatives and implications for CFTR modulation

2021 Scientific Reports  
We investigated the corrector effect of c407 and its derivatives on F508del-CFTR protein.  ...  Molecular docking and dynamics simulations combined with site-directed mutagenesis suggested that c407 stabilizes the F508del-Nucleotide Binding Domain 1 (NBD1) during the co-translational folding process  ...  The contacts between ligands and CFTR/NBD1 were analyzed by VLDM (Voronoi Laguerre Delaunay for Macromolecules) which represents a complex (protein/ligand) by a Laguerre tessellation [44] [45] [46] .  ...
