To successfully colonize and persist within a host niche, bacteria must properly regulate their gene expression profiles. The marine bacterium Vibrio fischeri establishes a mutualistic symbiosis within the light organ of the Hawaiian squid, Euprymna scolopes. Here, we show that the repressor NagC of V. fischeri directly regulates several chitin- and N-acetyl-D-glucosamine-utilization genes that are co-regulated during productive symbiosis. We also demonstrate that repression by NagC is relieved in the presence of N-acetyl-D-glucosamine-6-phosphate, the intracellular form of N-acetyl-D-glucosamine. We find that gene repression by NagC is critical for efficient colonization of E. scolopes. Further, our study shows that NagC regulates genes that affect the normal dynamics of host colonization.
