Web interfaces of SynechoNET. SynechoNET provides various user-friendly web interfaces and useful biological information. For instance, when users click 'sll0043' from category search page (a), the users can get a search result page displaying a list of highly reliable interaction partners of the clicked protein (b) as well as the candidate proteins predicted to interact with sll0043-encoded protein (c). When the users click the 'viewer' button in the search result page, a web page containing interactive Java applet viewer pops up to display the interaction network containing the selected protein (green box) and its interacting partners (yellow box) (d). Moreover, when the users click the 'M' button (violet box) in the search result page indicating a membrane protein, the information on protein domain structure (e) and transmembrane topology (f) of the selected protein, 'slr2104' will be displayed by Phobius and Localizome programs.
