Point mutations in a conserved region (TonB box) of Escherichia coli outer membrane protein BtuB affect vitamin B12 transport.

Uptake of cobalamins and iron chelates in Escherichia coli K-12 is dependent on specific outer membrane transport proteins and the energy-coupling function provided by the TonB protein. The btuB product is the outer membrane receptor for cobalamins, bacteriophage BF23, and the E colicins. A short se...
