Optimal simultaneous superpositioning of multiple structures with missing dataDouglas L Theobald
Department of Biochemistry, Brandeis University, MS009, Waltham, MA 02454, USA
Bioinformatics 28:1972-9. 2012..This practice is inefficient, as it ignores important data, and it fails to satisfy the common least-squares criterion. In the extreme, disregarding missing positions prohibits the calculation of a superposition altogether...
On universal common ancestry, sequence similarity, and phylogenetic structure: the sins of P-values and the virtues of Bayesian evidenceDouglas L Theobald
Biochemistry Department, Brandeis University, Waltham, MA 02454, USA
Biol Direct 6:60. 2011..The model selection tests prefer common ancestry for this artificial data set...
A formal test of the theory of universal common ancestryDouglas L Theobald
Department of Biochemistry, Brandeis University, Waltham, Massachusetts 01778, USA
Nature 465:219-22. 2010..These results provide powerful statistical evidence corroborating the monophyly of all known life...
Accurate structural correlations from maximum likelihood superpositionsDouglas L Theobald
Department of Biochemistry, Brandeis University, Waltham, Massachusetts, USA
PLoS Comput Biol 4:e43. 2008....
Empirical Bayes hierarchical models for regularizing maximum likelihood estimation in the matrix Gaussian Procrustes problemDouglas L Theobald
Department of Chemistry and Biochemistry, UCB 215, University of Colorado, Boulder, CO 80309, USA
Proc Natl Acad Sci U S A 103:18521-7. 2006..Our analysis generalizes, simplifies, and extends results from previous discussions of the ML Procrustes problem. An iterative algorithm is presented for the simultaneous, numerical determination of the ML solutions...
THESEUS: maximum likelihood superpositioning and analysis of macromolecular structuresDouglas L Theobald
Department of Chemistry and Biochemistry, University of Colorado at Boulder, Boulder, CO 80309 0215, USA
Bioinformatics 22:2171-2. 2006..AVAILABILITY: ANSI C source code and selected binaries for various computing platforms are available under the GNU open source license from http://monkshood.colorado.edu/theseus/ or http://www.theseus3d.org...
Divergent evolution within protein superfolds inferred from profile-based phylogeneticsDouglas L Theobald
Department of Chemistry and Biochemistry, UCB 215, University of Colorado, Boulder, CO 80309-0215, USA
J Mol Biol 354:722-37. 2005..This method extends phylogenetics into the challenging "twilight zone" of sequence similarity, providing the first objective resolution of deep evolutionary relationships among distant protein families...
Analysis of Drosophila TRPA1 reveals an ancient origin for human chemical nociceptionKyeongJin Kang
National Center for Behavioral Genomics, Waltham, Massachusetts 02454, USA
Nature 464:597-600. 2010..We propose that human pain perception relies on an ancient chemical sensor conserved across approximately 500 million years of animal evolution...
Nucleic acid recognition by OB-fold proteinsDouglas L Theobald
Department of Chemistry and Biochemistry, University of Colorado at Boulder, Boulder, Colorado 80309 0215, USA
Annu Rev Biophys Biomol Struct 32:115-33. 2003..Intriguingly, the observation of shared nucleic acid polarity may shed light on the longstanding question concerning OB-fold origins, indicating that it is unlikely that members of this family arose via convergent evolution...
Prediction of multiple tandem OB-fold domains in telomere end-binding proteins Pot1 and Cdc13Douglas L Theobald
Department of Chemistry and Biochemistry, University of Colorado at Boulder, Boulder, CO 80309, USA
Structure 12:1877-9. 2004..This common usage of multiple, tandem OB-fold domains in telomeric end binding proteins extends the known evolutionary conservation of eukaryotic end-protection mechanisms...
Structural basis for telomeric single-stranded DNA recognition by yeast Cdc13Rachel M Mitton-Fry
Department of Chemistry and Biochemistry, University of Colorado, UCB 215, Boulder, CO 80309-0215 USA
J Mol Biol 338:241-55. 2004..The structure reported here provides a foundation for understanding the mechanism by which Cdc13 recognizes GT-rich heterogeneous sequences with both unusually strong affinity and high specificity...
Nucleotide shuffling and ssDNA recognition in Oxytricha nova telomere end-binding protein complexesDouglas L Theobald
Department of Chemistry and Biochemistry, University of Colorado at Boulder, Boulder, CO 80309 0215, USA
EMBO J 22:4314-24. 2003..This set of structural and thermodynamic data highlights a fundamental difference between protein recognition of ssDNA versus dsDNA...
