Schematic diagram for genome regions surrounding spxB, ulaE and xfp locus in diverse lactobacilli. (A), spxB. (B), ulaE. (C), xfp. Gene syntenies were explored using the web service SyntTax . TDF-derived protein sequences were used to query the selected genomes. Genes corresponding to query proteins are drawn in bold. A consistent color coding allows identification of orthologs and paralogs. Some gene names are indicated. Normalized BLAST scores are visualized. Reference organisms: L. rhamnosus GG, L. casei ATCC 334, L. buchneri CD034, L. plantarum WCFS1, L. helveticus R0052, L. delbrueckii subsp. bulgaricus ATCC 11842 and L. brevis ATCC 367. For ulaE, a conserved gene order was observed only in L. rhamnosus GG and L. casei ATCC 334.
