Manuele Bicego, Stefano Danese, Simone Melzi, Umberto Castellani
2015 Lecture Notes in Computer Science  
In this paper we exploit the effectiveness of bioinformatics tools to deal with 3D shape matching.  ...  The key idea is to transform the shape into a biological sequence and take advantage of bioinformatics tools for sequence alignment to improve shape matching.  ...  The key idea consists of encoding the 3D shape as a biological sequence and employing tailored bioinformatics tools to perform the matching.  ...

Constructing patch-based ligand-binding pocket database for predicting function of proteins

Lee Sael, Daisuke Kihara
2012 BMC Bioinformatics  
Given a query pocket in a protein, Patch-Surfer searches a database of known pockets and finds similar ones to the query.  ...  Methods: In our previous work, we have developed an alignment free local surface-based pocket comparison method, named Patch-Surfer, which predicts ligand molecules that are likely to bind to a protein  ...  Two options were tested for the matching stage: the first approach matches all patches while the other approach matches only patches that are more similar than the predefined distance threshold value.  ...
