Figure 2From: PSAT: A web tool to compare genomic neighborhoods of multiple prokaryotic genomesLoss of function suggested by disruption of the leu operon. The leu operon is known to be involved with leucine biosynthesis in Francisella tularensis subspecies novicida U112 (ilvE, leuA, leuC, leuD, and leuB). The PSAT graphic demonstrated that genes in this operon are missing in Francisella tularensis subspecies tularensis SchuS4 suggesting that leucine biosynthesis may be impaired in this strain of the bacteria.Back to article page
