2.A.87.1.4 The riboflavin transporter of 203 aas and 5 TMSs, RibU or EcfS. Mediates
riboflavin and maybe also FMN, FAD and roseoflavin uptake (and efflux) (Light et al. 2018). Interacts with the energy-coupling
factor (ECF) module, EcfAA'T, which energizes transport of a number
of different substrates, each with its own EcfS subunit. Does not use an extracytoplasmic receptor (Karpowich et al. 2015). It provides extracellur FAD for an extracellular electron transfer process in firmicutes (Light et al. 2018).
