Aquaria, a web-based, molecular graphics resource, provides structural information for >500,000 protein sequences in SwissProt. For each protein sequence, Aquaria uses HHblits to pre-calculate alignments onto all available 3D structures. For a protein of interest Aquaria gives an overview of structural matches and displays the PDB structure with the maximum number of matching residues. At the same time, it loads annotations from several sources, including PredictProtein and SNAP2, to be mapped onto the structure. PredictProtein offers an array of structure and function predictions including solvent accessibility, transmembrane helices and strands, protein disorder, sequence conservation as well as protein and nucleic acid binding residues. SNAP2 predicts effects of single amino acid substitutions on protein functions. Aquaria displays per-residue mutational sensitivity, defined as high in case most mutations are strongly predicted to change function. A sequence overview in the structure viewer shows all sequence regions where matching structures can be found. This helps to switch to another structure if that allows better visualisation of an annotation of interest.
