URMS program for 3-D protein structure comparison
The algorithm compares the shapes of two proteins based on their alpha-carbon backbones. In this version, a single three-dimensional (3D) rigid motion is used to orient the proteins. This is in contrast to methods which allow different rigid motions for different portions of the proteins.
The algorithm is based on a unit-vector representation of the proteins. Instead of comparing alpha-carbon positions we compare direction vectors. The compared vectors are those between adjacent alpha-carbons along the protein backbone. Click here for more information.
