Transport of vitamin B12 in tonB mutants of Escherichia coli.
It is known that the tonB mutation in Escherichia coli is responsible for a defect in the transport of iron chelates. These are transported by systems that involve outer membrane components. We found that tonB mutants were also deficient in the secondary, energy-dependent phase of vitamin B12 transp...
