Vitamin B12 transport protein, molecular model showing secondary structure. This receptor protein, known as BTUB, is from the Escherichia coli bacterium. It accounts for active transport of vitamin B12 (cobalamin) across the outer membrane of the bacterial cell. This process explains how E. coli in human intestines can affect the uptake of vitamin B12. This single-chain protein contains 594 amino acids.
