Genetic map of O-antigen biosynthetic gene cluster 3 and 4 detected by AntiSMASH 3.0. The genes were designated by colors. Same color means equal genes in different strains; not colored means other genes. Cluster 3: 1. Transporter; 2. GntR family transcriptional regulator; 3. TetR family transcriptional regulator; 4. nucleotide sugar epimerase/dehydratase WbpM; 5. NAD-dependent epimerase/dehydratase family protein; 6. glycosyltransferase WbuB; 7. PREDICTED: UDP-glucuronic acid decarboxylase 6; 8. bifunctional UDP GlcNAc C6 dehydratase/C5 epimerase PseB; 9. CPS-53 (KpLE1) prophage; bactoprenol glucosyl transferase; 10. imidazole glycerol phosphate synthase subunit HisF; 11. LPS biosynthesis; 12. 3-oxoacyl-ACP reductase; 13. hypothetical protein; 14. pilin glycosylation protein PglB; 15. mannose-1-phosphate guanyltransferase beta. Cluster 4: 1. two-component sensor; 2. NAD(P)-dependent oxidoreductase; 3. hypothetical protein spr0320; 4. dTDP-D-glucose 4,6-dehydratase; 5. ethanolamine-phosphate phospho-lyase; 6. Epimerase; 7. pellicle/biofilm biosynthesis glycosyltransferase PelF
