Algorithm for rapid reconstruction of protein backbone from alpha carbon coordinates

Journal of Computational Chemistry, 18:80–85, 1997

Abstract

A method for generating a full backbone protein structure from the coordinates of α-carbons, is presented. The method extracts information from known protein structures to generate statistical positions for the reconstructed atoms. Tests on a set of proteins structures show the algorithm to be of comparable accuracy to existing procedures. However, the basic advantage of the presented method is its simplicity and speed. In a test run, the present program is shown to be much faster than existing database searching algorithms, and reconstructs about 8000 residues per second. Thus, it may be included as an independent procedure in protein folding algorithms to rapidly generate approximate coordinates of backbone atoms.
