Thus, prediction of protein flexibility from sequence or structural characteristics would assist in comprehension of the ways dynamics is linked to function, and would be important in protein modeling and design. In particular, quantitative description of side-chain dynamics would allow us to understand the role of side-chain flexibility in different functional processes, such as protein\u2013ligand and protein\u2013protein interactions.<\/jats:p>\n               <jats:p>Results: Using a dataset of 18 proteins, we trained a neural network for the prediction of methyl-bearing side-chain dynamics as described by the methyl side-chain generalized order parameters (S2) inferred from NMR data. The network uses 10 input parameters extracted from 3D structures. The average correlation coefficient between the experimental and predicted generalized order parameters is r = 0.71 \u00b1 0.029. Further analysis revealed that the order parameter depends more strongly on the methyl carbon packing density, the methyl carbon distance to the C\u03b1 atom, and the knowledge-based pair-wise contact potential between the methyl carbon and neighboring amino acids. In general, we observed an improvement in the prediction of methyl order parameters by our network in comparison with molecular dynamics simulations. The sensitivity of the predictions to minor structural changes was illustrated in two examples (calmodulin and barnase) by comparing the S2 predictions for the unbound and ligand-bound structures. The method was able to correctly predict most of the significant changes in side-chain dynamics upon ligand binding, and identified some residues involved in long-range communications or protein\u2013ligand binding.<\/jats:p>\n               <jats:p>Availability: \u00a0http:\/\/epigenomique.genopole.fr\/\u223ccarbonell<\/jats:p>\n               <jats:p>Contact: \u00a0antdelsol@gmail.com<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btp463","type":"journal-article","created":{"date-parts":[[2009,8,1]],"date-time":"2009-08-01T00:14:58Z","timestamp":1249085698000},"page":"2552-2558","source":"Crossref","is-referenced-by-count":7,"title":["Methyl side-chain dynamics prediction based on protein structure"],"prefix":"10.1093","volume":"25","author":[{"given":"Pablo","family":"Carbonell","sequence":"first","affiliation":[{"name":"1 Fujirebio Inc., Bioinformatics Research Unit, Research and Development Division,Komiya-cho, Hachioji-shi, Tokyo 192-0031, Japan and 2University of Evry, Epigenomics Program, Genopole, 523 Terrasses de l'Agora, 91034 \u00c9vry cedex, France"},{"name":"1 Fujirebio Inc., Bioinformatics Research Unit, Research and Development Division,Komiya-cho, Hachioji-shi, Tokyo 192-0031, Japan and 2University of Evry, Epigenomics Program, Genopole, 523 Terrasses de l'Agora, 91034 \u00c9vry cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio del","family":"Sol","sequence":"additional","affiliation":[{"name":"1 Fujirebio Inc., Bioinformatics Research Unit, Research and Development Division,Komiya-cho, Hachioji-shi, Tokyo 192-0031, Japan and 2University of Evry, Epigenomics Program, Genopole, 523 Terrasses de l'Agora, 91034 \u00c9vry cedex, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2009,7,30]]},"reference":[{"key":"2023013112123214100_B1","doi-asserted-by":"crossref","first-page":"235","DOI":"10.1093\/nar\/28.1.235","article-title":"The protein data bank","volume":"28","author":"Berman","year":"2000","journal-title":"Nucleic Acids Res."},{"key":"2023013112123214100_B2","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1016\/j.jmb.2005.03.001","article-title":"What contributions to protein side-chain dynamics are probed by NMR experiments?
