Modulation of iron-uptake systems by a mutation of luxS encoding an autoinducer-2 synthase in Vibrio vulnificus.

Abstract excerpt

Vibrio vulnificus possesses multiple iron-uptake systems which are mediated by VuuA (vulnibactin receptor), IutA (aerobactin receptor) and HupA (heme receptor). In this study, we determined the effect of a mutation of luxS encoding autoinducer-2 (AI-2) synthase on the expressions of the three receptors. A mutation and an in trans complementation of luxS did not affect the growing ability of V. vulnificus in...
