Structure Annotation Tools
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.

ESPript, Easy Sequencing in Postscript, is a utility to generate a pretty PostScript output from aligned sequences.

SPICE is a browser for protein sequences, structures and their annotations. It can display annotations for PDB, UniProt and Ensembl Peptides. All data is retrieved from different sites on the Internet, that make their annotations available using the DAS protocol. It is possible to add new annotations to SPICE, and to compare them with the already available information.
