Effect of iron concentration and growth rate on the expression of protein G in Pseudomonas aeruginosa.
Protein G of Pseudomonas aeruginosa was found to be strongly induced by iron and repressed by iron restriction in chemically defined medium (CDM). Expression in batch culture was influenced by phase of growth and in iron limited continuous culture by the doubling time. We suggest that protein G may constitute a low-affinity iron uptake system.
