'''BtuB''' is an outer membrane receptor found in a variety of bacteria, such as ''E. coli''. BtuB transports vitamin B12 across the membrane of gram-negative bacteria. The transport is achieved with high affinity by the collaboration of BtuB and the periplasmic protein TonB. | '''BtuB''' is an outer membrane receptor found in a variety of bacteria, such as ''E. coli''.
