Cloning and expression of the gene for the vitamin B12 receptor protein in the outer membrane of Escherichia coli.

The transport of cyanocobalamin (vitamin B12) in cells of Escherichia coli is dependent on a receptor protein (BtuB protein) located in the outer membrane. A 9.1-kilobase pair BamHI fragment carrying the btuB gene was cloned from a specialized transducing phage into multicopy plasmids. Insertions of...
