The European Bioinformatics Institute (EBI) Toolboxhttp://www.ebi.ac.uk/Tools/ Julie Pellegrini Introduction to Bioinformatics
What does the Toolbox include? • Homology and Similarity Programs • Protein Functional Analysis • Structural Analysis • Sequence Analysis • Miscellaneous Tools (clustering, visualization tools for gene expression)
Homology and Similarity Programs • Fasta • Nucleotide, protein, ion channels • BLAST • Nucleotide, protein, ‘Alternative Splicing’, vectors • Smith & Waterman • Protein sequence comparison • Databases • Proteomes, Genomes, Parasites, SNP
Protein Functional Analysis • InterPro • Protein Motif Database • InterProScan • Search InterPro by accession number or sequence • Search features • Protein repeats, motifs, biochemical function, family
Structural Analysis • Protein structure analysis and secondary structure prediction • DALI, MaxSprout • Active Site Search • NMR elucidation • Protein Quaternary Structure • PQS, PQS-Quick
Sequence Analysis • Unknown structure and function can be elucidated through comparison with database of known structures/sequences/functions • ClustalW • Global Multiple Alignment • EMBOSSALIGN • Like BLAST2 but Global • Gene finding tools • Translation tools • Promoter Analysis tools

What sorts of protein does my newly discovered gene code for?? • Paste discovered gene into Transeq to find protein sequence
How does our protein sequence compare with known cross-references? • Here is a Case for Sequence Alignments! • Use Align, ClustalW…
Align Output Findings We have in fact found what our gene codes for (YCA2) and it has already been added to the protein database.
