Hydrophilicity measures have been used extensively in the prediction of antigenic amino acid residues. Parker – uses the method of Parker et al., 1986, which is a hydrophilicity scale based on high-performance liquid chromatography retention times of model synthetic peptides.Residue hydropathy assignments are derived from water-vapor transfer free energies and the interior-exterior distribution of residue side-chains. The average is plotted at the midpoint of the window. Hydropathy values are assigned for all amino acids and are then averaged over a user-defined window. Kyte-Doolittle – predicts regional hydropathy of proteins from their amino acid sequences, using the approach of Kyte and Doolittle, 1982.Each residue is assigned a hydrophilicity value and these values are averaged over a hexamer window. Hopp and Woods, 1981, make two assumptions in using hydrophilicity to find antigenic determinants: 1) antigenic determinants are usually found on regions with a high degree of exposure to solvents and 2) antigenic determinants commonly possess charged hydrophilic side chains. Hopp-Woods – predicts protein antigenic determinants by searching protein sequences for the area of greatest local hydrophilicity.Protean 3D offers three methods for creating hydropathy profiles for protein sequence analysis: Use Protean 3D to have everything you need for comprehensive protein sequence analysis in one easy-to-use application! What’s more, Protean 3D is a complete protein sequence analysis software package, meaning that after you analyze and annotate your protein sequence, you can immediately perform protein structure analysis, as well as predict protein structure, perform antibody modeling, or evaluate protein-protein docking interactions. ![]() The protein sequence analysis tools available in Protean 3D provide elegant graphical representations of the applied methods, making it simple to analyze biophysical properties, predict secondary structures such as B-cell epitopes, calculate surface probability, perform amino acid composition analysis, and more. Protein sequence analysis is essential for studying and predicting protein function and structure, but often protein sequence analysis tools lack the visualization component necessary for interpretation, or they require additional tools for downstream analysis. Upon completion of the course, students have extensive skills with sequence analysis tools and are prepared for their own laboratory projects or bioinformatics software creation.Use Protean 3D for comprehensive protein sequence analysis in one easy-to-use application! Throughout the semester, interesting biological questions are addressed by analyzing sequences, searching databases, using sophisticated software, and interpreting results. Students learn how to evaluate data sources and choose the correct paths to solutions. Classes consist of lecture and extensive hands-on work using mainstream web-based bioinformatics tools. This course teaches the bioinformatics skills used in academic, biotech, and pharmaceutical laboratories for analyzing individual DNA and protein sequences. The details of this data reveal basic information such as gene and protein structures, and may lead us to major discoveries like gene-disease associations. With breakthroughs in biotechnology such as high-throughput and inexpensive DNA sequencing, we are collecting vast amounts of data that will be analyzed for years to come.
