Description (originally from EcoCyc[2]) L-ascorbate transporting phosphotransferase system
Comments (originally from EcoCyc[1]) SgaTBA, a putative PTS permease, belongs to the functional superfamily of the phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system (PTS). The PTS transports and simultaneously phosphorylates its sugar substrates in a process called group translocation. SgaTBA presumably takes up an exogenous sugar, releasing the phosphate ester into the cell cytoplasm in preparation for metabolism [3][4][5][5][3][4][5] indicate that all three components are necessary for the uptake and utiliztion of L-ascorbate in vivo as well as for the phosphorylation of L-ascorbate in vitro.
