G377E and Y515C showed the highest damaging impacts on the biological activity of ACE2. Docking showed few effects of these nsSNPs in altering the binding affinity of ACE2 with SARS-CoV-2 spike. All these risky amino acid alterations were found in extremely low-frequency worldwide. Structure-based tools showed damaging effects of C141Y, and N599K. All sequence-based in silico tools indicated damaging impacts of V184G, A191P, P235R, P263S, G268C, G377E, Y515C, G466W, and L595V. This study was conducted to predict the most deleterious non-synonymous single nucleotide polymorphisms (nsSNPs) on ACE2, assess their frequency among populations, and evaluate their effect on the binding with the SARS-CoV-2 spike. A damaged ACE2 could alter the rate of this viral infection. This protein provides the entry point through which COVID-19 hooks and infects human cells. Each C-alpha point is typically shared as a vertex by several tetrahedra as a result of their packed arrangement hence, each amino acid may simultaneously participate in a number of distinct nearest neighbor residue quadruplets.Īngiotensin-converting enzyme 2 (ACE2) is a well-established functional host receptor for the highly devastating ongoing pandemic of coronavirus disease 2019 (COVID-19). Shown here is the modified tessellation obtained by removing all edges longer than 12 Å, which reveals clefts and pockets on the protein surface and ensures that each tetrahedron identifies a quadruplet of interacting amino acid residues at its four vertices via their C-alpha coordinates. The complete tessellation yields hundreds of solid tetrahedra that are packed against one another in the form of a convex hull, filling the space otherwise occupied by the protein structure. A 3D tetrahedral tiling is then obtained by using these C-alpha points to serve as vertices. Initially, the protein is represented as a discrete set of points in 3D space, corresponding to the C-alpha atomic coordinates of every amino acid residue in the structure. Included among these upgrades is the ability to perform three highly requested tasks: to run 'big data' batch jobs to generate predictions using modified protein data bank (PDB) structures, and unpublished personal models prepared using standard PDB file formatting and to utilize NMR structure files that contain multiple models.ĭelaunay tessellation of the HIV-1 reverse transcriptase enzyme (PDB ID: 1rtjA).

Nevertheless, all the codes have been rewritten and substantially altered for the new portable software, and they incorporate several new features based on user feedback. These five command-line driven tools, as well as all the supporting programs, complement those that run our AUTO-MUTE web-based server.

Two additional classifiers are available, one for predicting activity changes due to residue replacements and the other for determining the disease potential of mutations associated with nonsynonymous single nucleotide polymorphisms (nsSNPs) in human proteins. Three of the predictors evaluate changes to protein stability upon mutation, each complementing a distinct experimental approach.

#Automute protein software

The AUTO-MUTE 2.0 stand-alone software package includes a collection of programs for predicting functional changes to proteins upon single residue substitutions, developed by combining structure-based features with trained statistical learning models.
