Bacterial ABC Transporter Involved in B12 Uptake
The structure was published by Locher, K.P., Lee, A.T., and Rees, D.C., in 2002 in a paper entitled "The E. coli BtuCD structure: a framework for ABC transporter architecture and mechanism." (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 2002.
The experimental data on which the structure is based was not deposited.
