additional information | Escherichia coli | the sgaTBA genes of Escherichia coli encode a putative 12-transmembrane alpha-helical segment transporter, an enzyme IIB-like protein and an enzyme IIA-like protein of the phosphotransferase system, respectively. All three proteins as well as the energy-coupling phosphotransferase system proteins, enzyme I and HPr, are required for the anaerobic utilization and uptake of L-ascorbate in vivo and its phosphoenolpyruvatedependent phosphorylation in vitro | ? | - |
