Abstract
Provided is an apparatus and method for comparing a protein structure, which can search a protein similar to an inquiry protein in a 3D protein database in real time by describing a feature of a protein structure by using a three-dimensional (3D) relative directional angle (RDA) and a Fourier descriptor. The apparatus includes: a 3D RDA coder configured to code a 3D RDA of a target protein data or an inquiry protein data inputted from the outside; a Fourier transformer configured to obtain Fourier coefficients by Fourier transforming 3D RDA coding values coded by the 3D RDA coder; a comparator configured to compare the obtained Fourier coefficient of the target protein data with the obtained Fourier coefficient of the inquiry protein data; and a data generator configured to output protein data in order from high similarity to low similarity according to the comparison result of the comparator.
