Contents
ECF transporters are required for the uptake of micronutrients such as cofactors (vitamins), metal ions, or amino acids. The transporters are composed of three general components (membrane spanning T protein und two ATP-hydrolyzing A proteins) and substrate-specific S proteins.
In B. subtilis, there are four known substrates for ECF transporters, riboflavin, thiamine, biotin, and tryptophan.
The general components of the ECF transporters
- ybxA ATP-binding A1 protein (EcfA1)
- ybaE ATP-binding A2 protein (EcfA2)
- ybaF membrane-spanning T protein (EcfT)
The substrate-specific S components of the ECF transporters
- RibU: uptake of riboflavin
- ThiT: uptake of thiamine
- YhfU: uptake of biotin
- TrpP: uptake of tryptophan
- YuiG: unknown specificity
