Model showing the effect of disrupting the cj1387c-cj1388-cj0327 genes on autoagglutination (AAG). Strains are shown ranked in the order in which AAG is decreased in media supplemented with Tween 20 compared to un-supplemented media. Cj1388 expression is proposed to be de-repressed when cj1387c is inactivated resulting in greater AAG, which cannot be disrupted by Tween. Deleting both cj1388 and/or cj0327 results in a Tween-dependent decrease in AAG. Complementation by Cj1388 rescues this phenotype, and this activity is dependent on a single cysteine residue in Cj1388, which forms a dis- sulfide-linked dimer in vitro. AAG is dependent on flagella glycan decoration, suggesting that Cj1388 and Cj0327 have a role in mediating glycan modification of flagella.
