We developed a deductive database system PACADE for analyzing three dimensional and secondary structures of protein. PACADE is equipped with a function to search for similar structures in proteins. Unlike other approaches based on calculation of the inter-atomic root mean square distance, this function is based on logic programming and source level rule rewriting techniques.
