BiasViz -- visualization of amino acid biased regions in protein alignments
What you can do:
A tool to graphically study local amino acid composition in protein sequences of a multiple sequence alignment.
Highlights:
- About a third of all protein sequences have at least one composition biased region (CBR).
- Such regions might act as linkers between protein domains but often confer specific binding to various molecules; therefore, their characterization in terms of their boundaries and over-represented residues is important.
- Analysis of CBRs in a particular sequence can be time consuming if several types of biases have to be explored and their position visualized.
- Assessment of the significance of the detected CBRs can be approached by comparison to homologous protein sequences.
Keywords:
- amino acid bias
- protein sequence alignment
- composition biased region
