This paper-discusses the implementation of a three-dimensional (3D) structure motif search of proteins. Each protein structure is represented by a set of secondary structure elements (SSEs) which involves alpha-helix segments and beta-strand segments. In describing it, every SSE is further reduced into a two-node graph that consists of the starting amino acid residue, the ending residue and a pseudo-bond between them. The seal-ching algorithm is based on a graph theoretical clique-finding algorithm that has been used for 30 substructure searching in small organic molecules. The program SS3D-P2 was validated using proteins that have well-known 30 motifs, and it correctly found the Greek key motif within an eye lens protein, crystallin, that consists of four anti-parallel beta strands. The program was also successfully applied to searching for the more complex 30 motif, TIM-type beta-barrel motif, with a protein structure database from the Protein Data Bank.
