Bioinformatics for Protein

Bioinformatics plays an important role in all aspects of protein analysis, including sequence analysis, structure analysis, and evolution analysis. In sequence analysis, several bioinformatics techniques can be used to provide the sequence comparisons, in which new sequences can be compared to those with known functions to study the biology of an organism. In structure analysis, many available databases and bioinformatics techniques can help to find the factors governing the folding and stability of proteins and to predict the secondary structures from amino acid sequence. In evolution analysis, we use the technique like phylogenetic trees to find homologous proteins and conservative functional regions. With bioinformatics techniques and databases, function, structure and evolutionary history of proteins can be easily identified.

Bioinformatics for Protein at Creative Proteomics

Bioinformatics has been applied to protein research for many years and has made great contributions in sequence, structure and evolution analysis of proteins. At Creative Proteomics, we can provide various professional bioinformatics techniques for protein analysis.

Bioinformatics for ProteinClustering of amino acids

Protein Sequencing Analysis Services

The analysis of protein sequences provides the information about the preference of amino acid residues and their distribution along the sequences for understanding the secondary and tertiary structures of proteins and their functions. Besides, the identification of conserved regions in protein sequences can help to predict the structurally or functionally important regions. We provide several tools for protein sequence analysis, such as PSI-BLAST (Position-Specific Iterative BLAST), a more suitable method to search a database of sequences similar to a query sequence, and ClustalW, which is a multiple sequence alignment program for biomolecules.

Protein Structure Analysis Services

The analysis on protein structures provides information about the factors associated with the folding and stability of proteins, the interactions between amino acid residues and with the surrounding medium, the preferred amino acid residues in protein environment, and the location of residues in the interior/surface of a protein and amino acid clusters. The information obtained from the protein structure analysis is useful for predicting the secondary and tertiary structures of proteins. In addition, secondary structure information can be used to predict three-dimensional structures of proteins and protein stability upon mutations. We use ACCESS to compute ASA (The solvent accessible surface area) and Naccess to calculate the atomic accessible area.

Protein Evolution Analysis Services

The analysis of protein evolution provides the information about homologous protein, functionally conserved regions, and the evolutionary history of protein. We use the phylogenetic tree for the protein evolution analysis. Phylogenetic tree, which consists of a root (the last common ancestor of the protein family), nodes, branches, and tips, can use the ancestral protein sequence reconstruction to infer the history of a protein family and detect the coevolution between protein families. The phylogenetic tree can be constructed and analyzed with robust scripting tools, which include R package “APE”(Analyses of Phylogenetics and Evolution), ETE (a Python Environment for phylogenetic Tree Exploration) and Bio.Phylo for Biopython. We will choose the best tool for specific requirements.
