title: Prot-2S: a new python web tool for protein secondary structure studies.
abstract: Prot-2S is a bioinformatics web application devised to analyse the protein chain secondary structures (2S) (http:/ /www.requimte.pt:8080/Prot-2S/). The tool is built on the RCSB Protein Data Bank PDB and DSSP application/files and includes calculation/graphical display of amino acid propensities in 2S motifs based on any user amino acid classification/code (for any particular protein chain list). The interface can calculate the 2S composition, display the 2S subsequences and search for DSSP non-standard residues and for pairs/triplets/quadruplets (amino acid patterns in 2S motifs). This work presents some Prot-2S applications showing its usefulness in protein research and as an e-learning tool as well.
