Genetic map of colanic acid biosynthetic gene cluster 2 detected by AntiSMASH 3.0. The genes were designated by colors. Same color means equal genes in different strains; not colored means other genes. 1. Thiosulfate sulfurtransferase; 2. transcriptional regulator; 3. nucleotide sugar dehydrogenase; 4. colanic acid production tyrosine-protein kinase; autokinase; Ugd phosphorylase; 5–7. hypothetical protein; 8. putative acyl transferase; 9. Glycosyl transferase; 10. GDP-D-mannose dehydratase, NAD(P)-binding; 11. bifunctional GDP-fucose synthetase: GDP-4-dehydro-6-deoxy-D-mannose epimerase/ GDP-4-dehydro-6-L-deoxygalactose reductase; 12. colanic acid biosynthesis glycosyl transferase WcaI; 13. mannose-1-phosphate guanylyltransferase/mannose-6-phosphate isomerase
