3.A.1.25.5
Biotin/Riboflavin ECF transport system, EcfAA'T/RibU/BioY (Karpowich and Wang 2013). RibU binds riboflavin with high affinity, and the protein-substrate complex is
exceptionally stable in solution. The crystal structure of riboflavin-bound RibU reveals an
electronegative binding pocket at the extracellular surface in which the substrate is completely
buried (Karpowich et al. 2016).
