1. A method, comprising:
- acquiring site coordinates and neighboring information for a receptor site of a given protein or a ligand;
determining principal curvatures and directions for each coordinate point of the receptor site or the ligand;
determining maximum span for the receptor site or the ligand;
iterating for each remaining site coordinate of the receptor site or the ligand; and
indexing the given protein, the site coordinates, the neighboring information, the points, the principal curvatures and directions, the maximum span, and the receptor site or the ligand in a data store.

Abstract
Architectures, queries, data stores, and interfaces for proteins and drug molecules are provided. Active and binding sites or proteins and drug molecules are modeled and indexed in a data store. The data store may be browsed, searched, and mined to find specific proteins or to find potential drug molecules that interact with the proteins in response to the active and binding sites.
