Determination of Characteristic Frequency in Proteins using Chirp Z-transform

Proteins perform their functions by interaction with other molecules known as target. Protein-target interactions are very specific in nature and occurs at pre defined locations in proteins known as hotspots. For successful protein-target interaction both protein and target must share common spectral component known as characteristic frequency. Characteristic frequency is of utmost importance since it forms basis for protein-target interactions, thus an approach for determination of characteristic frequency in proteins using chirp Z-transform is illustrated in this paper.
