![]() ![]() Not satisfy this property, but at least one simplex edge connects the Triangular face of a simplex, and if that triangular face is not sharedīy another simplex, then the position is referred to as being on the Surface. If a mutated position participates as a vertex in a Is calculated for all simplices in which the mutated position serves asĪ vertex. Quantities yielding models which perform equally well. Position as an attribute, we compute the following tessellation-based Of including relative solvent accessibility (RSA) of the mutated Two sets of attributes for the six nearest neighbors is identical to Nearest neighbors and the mutated residue. Nearest neighbors, and the ordered differences between the primary Finally, we also utilize the wild type and replacement aminoĪcid identities, the ordered identities of the amino acids at the six Ordered by simplex edge-length Euclidean distance away from the mutated Positions that participate in simplices with the mutated position, Next, we include the EC scores of the six nearest-neighbor The mutated position, also referred to as the residual score of the mutant Set of attributes for single residue substitutions across all (environmental change) scores that quantify perturbations at theĬorresponding residue positions in the protein. Vector difference of these profiles (mutant - wild type) as the residual profile of the mutant ![]() Potential profile relative to the wild type profile. Participate as vertices in simplices with the mutated position, willĮxperience alterations in their environment scores in the mutant 3D-1D Mutated residue position, as well as all neighboring positions that Position of interest and re-computing the environment scores. Mutagenesis is defined by changing the residue label at a Type protein structure, a novel computational By utilizing the tessellation of the wild Participates as a vertex, yielding a 3D-1D Log-likelihood scores of all simplex quadruplets in which it Propensity of occurrence for each quadruplet type.Ĭalculated for every amino acid in a protein by summing the Occurrence (p ijkl) for each quadruplet type. The multinomialĭistribution (n = 4) is used to also compute an expected rate of Possible from the 20 naturally occurring amino acids. Normalized frequencies of occurrence (f ijkl)Īre calculated for each of the 8855 order-independent quadruplets Structure similarity obtained from the Protein Over 1400 high-resolution x-ray structures with low sequence and The approach is applied to a training set of To safeguard against quadruplets that do not interactīiologically, only tetrahedra whose six edges are all less than 12Īngstroms are considered. Space and identify quadruplets of nearest-neighbor amino acids in each Points are utilized as vertices for tetrahedral simplices that tile the Tessellation to each discretized protein structure, whereby the Protein structures are reduced to collections of points inģ-dimensional space, whose coordinates are those of amino acidĪlpha-carbon atoms. Details concerning the datasets used forĪdditional documentation linked to the respective server pages, and These include Random Forest, Support Vector Machine (SVM),ĪdaBoostM1 combined with the C4.5 Decision Tree algorithm, as well as Regression models have been developed and are available for Type of function prediction, a variety of classification and Provide more accurate predictive models of mutant protein function.

The unzipped AutoMute2 folder contains the file weka.jar, to which the computer's CLASSPATH environment variable must point (requires advanced computer skills).
