The table at right lists genes that may be "functionally linked to" (i.e., participate in a common biological process, or form a protein complex with) the subject gene of this page, as determined by two sequence-independent methods, including phylogenetic profiling and operon membership (determined by OperonDB). (Info.) These linkages may also be viewed graphically using the program VisANT, by clicking on the headers of the table. Note: VisANT requires Java.
