Summary

This computer package uses a Fast Fourier Transform (FFT) algorithm to locate residue periodicities in either protein or DNA sequences.

The search and study of residue periodicities in protein sequences is a powerful tool for the structural and functional study of proteins, whose spatial conformation has not been solved yet. Such periodicities may reveal the existence of repeating patterns and help towards an understanding of the molecular structure of a fibrous/structural protein. Also, they may reveal ways of assembly of such proteins. Periodicities in DNA may dictate structural and functional characteristics of the molecule.
