Enterobactins iron deficiency

These apparent contradictions raised some intriguing questions. How does E. coli, growing aerobically under iron deficiency when the entC gene is fully derepressed, prevent the synthesis of MK. Furthermore, under anaerobic conditions, how does E. coli prevent the synthesis of enterobactin when MK synthesis is induced. This... 

Another example of iron uptake by Escherichia coli monitored by M5ssbauer spectroscopy was performed by Matzanke et al. As the iron deficiency under aerobic conditions is mediated by a highly stable ferric enterobactin [Fe(ent) ]...
