ssm

SSM is a macromolecular coordinate superposition library, written by Eugene Krissinel. The library implements the SSM algorithm of protein structure comparison in three dimensions, which includes an original procedure of matching graphs built on the protein's secondary-structure elements, followed by an iterative three-dimensional alignment of protein backbone Calpha atoms. The algorithm implemented by the software is described in: E. Krissinel & K. Henrick (2004) Secondary-structure matching (SSM), a new tool for fast protein structure alignment in three dimensions. Acta Crystallogr D Biol Crystallogr. 60, 2256-68. This package contains the shared library components needed for programs that have been compiled with the ssm library.
