An approach to detection of protein structural motifs using an encoding scheme of backbone conformations.

This paper presents an approach to detection of protein structural motifs. In our approach, first all protein backbone conformations are converted into character strings using an encoding scheme. Then we use the Smith-Waterman local alignment algorithm to detect common structural motifs. By comparing results with the PROSITE regular expression patterns, our method can detect several motifs which the PROSITE patterns fail to detect.
