  2.3.1.209 | metabolism |
dTDP-D-Qui4N is synthesized from alpha-D-glucose-1-phosphate in three reaction steps catalyzed by glucose-1-phosphate thymidyltransferase (RmlA), dTDP-D-glucose 4,6-dehydratase (RmlB), and dTDP-4-keto-6-deoxy-D-glucose aminotransferase (VioA). An additional acetyltransferase (VioB) catalyzes the conversion of dTDP-D-Qui4N into dTDP-D-Qui4NAc, biosynthetic pathway, overview |

| 2.3.1.209 | physiological function |
glycosylation of Xagellin contributes to swimming and swarming motilities, adhesion ability, and consequently virulence with glycan structure at position Ser 201 harboring two L-rhamnoses and one modified 4-amino-4,6-dideoxyglucose, i.e. viosamine. Genes vioA, vioB, and vioT are essential for glycosylation of flagellin, and accordingly are required for bacterial virulence, e.g. on Nicotiana tabacum |
