Comments on 1l7v » ABC transporter BtuCD, symmetric structure
Part of the ABC transporter complex btuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system. The complex is composed of two ATP-binding proteins (btuD), two transmembrane proteins (btuC) and a solute-binding protein (btuF - not present in the crystal structure).
