additional information To demonstrate that the variable regions determine substrate specificity and to investigate which of the variable regions of R1,2-FucT is responsible, six chimeric R1,2-FucTs are constructed by domain swapping between Escherichia coli FucTs WbsJ and WbwK. Three chimeras are inactive, the other three chimeras have greater substrate spectra than FucT WbwK but lower activity than WbsJ. Escherichia coli

wbwK gene encoding an alpha1,2fucosyltransferase in Escherichia coli which is only active with substrates containing the Galbeta1,3GalNAcalpha-structure (T-antigen) to form H-type 3 blood group antigen (Fucalpha1,2Galbeta1,3GalNAcalpha-OR) but not with Galbeta-OMe Escherichia coli

General Information

General Information Comment Organism
physiological function Some Escherichia coli strains display human blood group antigens, so called O-antigen structures, on their cell surface to evade the immune system of the human host. alpha1,2fucosyltransferase are involved in the biosynthesis of O-antigen structures. Escherichia coli
