FIG 3.

Schematic genetic organization of polysaccharide biosynthesis of eps gene clusters in L. paraplantarum BGCG11. ORF1 is a putative priming glycosyltransferase (black arrow). Other glycosyltransferases are indicated with dark gray arrows (ORF2, eps4G, epsH, welL, and ORF8); lighter-gray arrows indicate genes putatively involved in polymerization and the export process in EPS-CG11 biosynthesis (wzx and eps11O); arrows with hatched lines indicate genes putatively involved in the regulation of EPS-CG11 biosynthesis (cps2A, wzz, and capC). The transposase tnp separates the above-mentioned genes from the rfbACBD gene cluster (indicated by arrows with horizontal stripes) putatively involved in the synthesis of dTDP-rhamnose.
