Figure 8. Coincidence matrix for E. coli Lsr system LMNAST stringent search hits.

This coincidence matrix depicts the subset of hits with a mean element homology >0.3 and also containing 4–6 gene characters. This subset was chosen for its intermediate degree of homology to the query Lsr system. LsrF and lsrG characters were found to be overrepresented among these hits coincident to hits also containing lsrR and lsrK characters.
