Abstract
In molecular biology, retrieval of 3D protein structures is a very important topic. In this paper. From the view of geometry, we propose three types of characteristics (e.g. VDP,DDP,ADP) for describing 3D protein structures in order to perform similarity search and classification. The goal of the approach is to reduce the 3D protein structures matching problem to the comparison of the probability distribution. Experimental results show that our method is robust and invariant with respect to translation, rotation.
