Figure 4. LAC-4 K locus gene organization and functional assignment.

Figure 4

GI12 harbors genes of K locus in LAC-4. Color coding scheme follows that of Hu et al63. Two of the three-sugar repeating unit recently determined for LAC-4 surface polysaccharide36 can be produced via reactions catalyzed by gene products of the genes in the cluster (bottom). The product of wafP gene probably catalyzes the formation of the 1 → 3 glycosyl bond between α-L-FucNAC and α-D-GlcNAc. The wbpV gene (marked by *) is a pseudogene (with two separate ORFs) as a result of a point mutation.
