We have been developing an interactive database system for three dimensional protein structures named PROTEIX. The most important feature of PROTEIX is that it has pattern matching facilities for three dimensional protein structures. For example, such functions as substructure search and alignment of two protein structures are included. As well as such functions, PROTEIX has the following facilities: a mechanism for inputing a file in PDB (Protein Data Bank) data format, an interactive graphic interface, and various pattern matching functions for amino acid sequences (strings).
