Expression

Organism Comment Expression
Vibrio vulnificus the Fe-S cluster regulator IscR senses iron starvation as well as reactive oxygen species and shifts to the Fe-S clusterless apo-form, which leads to the increase of cellular IscR and in turn prx3 expression, contributing to the survival and virulence of Vibrio vulnificus during pathogenesis up
