摘要Ferric uptake regulator (Fur) is an important transcriptional regulator of Gram-negative bacteria. Edwardsiella tarda is a severe fish bacterial pathogen with a broad host range that includes humans. In this study, we examined the regulatory function of Fur in E. tarda via a proteomic approach. Compared to the wild type TX01, the fur mutant TX01 Delta fur exhibited (i) retarded growth, (ii) enhanced siderophore production, (iii) increased acid tolerance, which is in contrast to observations in other bacterial species, (iv) decreased survival against oxidative stress and host serum, (v) impaired ability to inhibit host immune response, (vi) attenuated tissue infectivity and overall virulence. The deficiency of TX01 Delta fur was rescued by introduction of an exogenous fur gene. iTRAQ-based comparative proteomic analysis of TX01 Delta fur and TX01 identified 89 differentially expressed proteins that cover a wide range of functional categories including those affected by fur mutation. In addition, 16 proteins were identified for the first time to be regulated by Fur in Gram-negative bacteria. These results provide the first protein based interpretation of the global impact of Fur on the physiology and infectivity of E. tarda.
