Structure searches

Inhibition can be reversible when it simply complexes at the active site preventing further catalysis. The active enzyme under these conditions can be recovered by dialysis. Another form of inhibition is the irreversible type where the active enzyme cannot be recovered by dialysis. A variant of this type of inhibition is suicide inhibition a substrate of the enzyme reacts at the active site to yield an irreversible inhibitor which then reacts directly with groups at the active site [18]. A technique, in situ click chemistry , is related to that of suicide inhibition and involves click chemistry components which complex at the active site of an enzyme and combine to form femtomolar inhibitors. The technique can be used to synthesise inhibitors or by selection from a library of click chemistry components to search structure space of the inhibitor for the drug target [ 19].

An appropriate database for the initial model requires an extremely high structural diversity to cover all of the structural features that can occur in the compound type to be investigated. Although diversity is important, it is generally a good idea to generate type-specific databases that represent the searched structure type the best. 

Attachments Any type of file information that can be attached to a section similar to e-mail attachments. Examples are texts in a generic format, chemical structures, spectra, chromatograms, and images. These attachments should be searchable using the appropriate search functionality, such as full-text search, structure search, or spectrum.

The first major graphics application for an ACS publication automated the input and composition of structures in CA. Later, this structure input method was modified and added to the Messenger software for use in STN International as the basis for the STRUCTURE command that builds queries for substructure searching. After a search, structure images can be displayed on certain graphics terminals. Chemical structures are also produced by Messenger batch software on STN International off-line prints. 

All of these methods currently utilize a search structure generally called the Heuristic Search Method. 

Trie Tree data structure employing (1) repeated subscripting, and (2) different numbers of node successors. A data structure that is particularly useful for multiway search structure from information retrieval useful means for search of linguistic data.
