OlfactionBase

OlfactionBase is a manually-curated comprehensive database that incorporates multidimensional facets of major components involved in the olfaction process, i.e., odors, chemicals (both odorants and odourless), Olfactory Receptors (ORs), odorant-OR interaction, and other associated proteins (odorant-binding proteins (OBPs), pheromone binding proteins (PBPs), and chemosensory proteins). OlfactionBase collates information from different resources. OlfactionBase offers several navigation and data retrieval options like Olfaction Wheel and interlinked textual and drawing based (for chemical structure) search options.

The Olfaction Wheel allows the user to browse through the odor classifications interactively, backward and forward, to access corresponding odorant molecules, odorant's chemical profile and interacting ORs.
