A member of the second carbohydrate uptake subfamily of ATP-Binding cassette transporters is responsible for Ribonucleoside uptake in Streptococcus Mutans

Streptococcus mutans has a significant number of transporters of the ATP-binding cassette (ABC) superfamily. Members of this superfamily are involved in the translocation of a diverse range of molecules across membranes. However, the functions of many of these members remain unknown. The authors have investigated the role of the single S. mutans representative of the second subfamily of carbohydrate uptake transporters (CUT2) of the ABC superfamily.
