The data on this page are organised in three major sections: (1) analysis of residue conservation across the entire superfamily, (2) analysis of residue conservation in functional sub-groups (FSGs) that group together protein domains with similar functional mechanisms but not necessarily identical specificities (3) analysis of residue conservation within families of protein domains sharing identical functional specificities
Each structural alignment presented on this page is in FASTA format, with the amino acid sequence of each protein structure displayed one at a time with the sequence reading from left to right across the page. Conservation scores on this page were generated using Scorecons. The conservation scores files show the same structural alignment as the FASTA files, but the protein sequences are displayed in columns, each column corresponding to one protein sequence, with the sequence going from top to bottom. The first column shows the conservation score. This ranges from 0 for unconserved residues to 1 for the most highly conserved. In all alignment files, sequences are identified by a CATH domain ID if they represent domains classified in CATH, or by a unique MD5 string that is used as identifier in the Gene3D database otherwise.
The first link for each FSG presented here is of an image file of this alignment with catalytic residues shaded brown and ligand binding residues shaded light blue. Conservation scores for each position in the alignment is calculated using the algorithm scorecons and are shown as a histogram underneath the alignment. The consensus secondary structure as predicted by jpred is also displayed underneath the alignment. Some of the structural alignments contain a large number of sequences, in which case you may find you have to use the zoom function to view the image in your browser. The raw FASTA file containing the alignment can be downloaded by following the second link. The last two link display the raw data from the scorecons algorithm, with annotated catalytic residues and ligand-binding residues in the first and second links, respectively. See general page description above for more details on file formats. Functional residues (for example a catalytic residue or a ligand binding residue) are shown in lower case.
Here, we provide raw text FASTA files as well as scorecons output files for each specificity group. Specificity groups are grouped together according to the FSGs to which they belong. N/A indicates that no specificity groups alignments with known functional residues could be found for the given FSG. See general page description above for more details on file formats.
