SAS - Sequence Annotated by Structure
SAS is a tool for applying structural information to a given protein sequence. It uses FASTA to scan a given protein sequence against all the proteins of known 3D structure in the Protein Data Bank (PDB). The resultant multiple alignment can be coloured according to different structural features and the matching 3D structures can be superimposed and viewed in RasMol.
Use the form below to identify your protein sequence of interest by: a) providing a PDB code, b) providing a UniProt code or accession number, c) pasting in your sequence, or d) uploading a PDB file. By default the whole PDB will be searched, but you can restrict the search using the Search Option box at the bottom.
Choose option a, b, c or d:
