Figure 4: The EcoCyc linear map browser. Sections of the chromosome are shown at three resolutions. In the rightmost section, the coding region for each gene is shown with a vertical line. The linear partial map allows an investigator to examine map relationships among subsets of E. coli genes by beginning with a display of the chromosome with no genes present, and selectively adding genes to the window. The genes to be added can be selected by several criteria: by name (such as hisE); by matching a substring " against all gene names (such as his"); as members of one of the classes of all E. coli genes defined by Riley [20]; or the set of genes coding for enzymes in a chosen biochemical pathway. The user can consecutively add sets of genes according to these criteria, and can undo previous add operations in reverse order. For example, the user might add all genes in the biosynthetic pathways for tryptophan, tyrosine, and phenylalanine, and then add all genes coding for membrane proteins. The zoom capabilities described in conjunction with the full map also work for the partial map. The second tool displays the full map in circular form, with similar zooming capabilities. 57
58 Retrieval Operations EcoCyc provides the user with two classes of DB retrieval operations: direct retrieval through menus of predefined queries, and indirect retrieval through hypertext navigation [ 13]. For example, imagine that a user seeks information on the hisA gene, such as its map position and information about the enzyme it encodes. EcoCyc allows the user to call up an information window for that gene directly by querying the gene name. The indirect approach consists of hypertext navigation among the information windows for related objects. Such navigation allows the user to find the hisA gene by traversing many paths through the DB. The user could issue a direct query to display the biosynthetic pathway for histidine, and then click on the name of the enzyme at the last step in the pathway. The resulting information window for that enzyme shows the name of the gene (hisA) coding for the enzyme. Clicking on the gene name displays the information window for (hisA). Alternatively, the user could query the compound histidine by name. The resulting window lists all reactions involving histidine; the user can click on a reaction to navigate to its window, which lists all enzymes that catalyze the reaction, plus all genes encoding those enzymes (including hisA). Software Architecture and Distribution EcoCyc is implemented in Common Lisp with a graphical-interface toolkit called the Common Lisp Interface Manager (CLIM). The architecture of the EcoCyc development environment is shown in Figure 5. EcoCyc is available under license through the WWW, as a program that runs on the Sun workstation, and as a set of flat files. See the EcoCyc WWW pages at URL http://www.ai.sri.com/ecocyc/ for more information.
