theoretic methods for the analysis of structural relationships in
biological macromolecules |
|
Subgraph
isomorphism and maximum common subgraph isomorphism algorithms from
graph theory provide an effective and efficient way of identifying
structural relationships between biological macromolecules. They
thus provide a natural complement to the pattern matching algorithms
that are used in bioinformatics to identify sequence relationships.
Methods available here are applicable to different types of biological
macromolecules from carbohydrates to protein and nucleic acid structures.
