LITERATURE
during growth on fructose, the gene cluster HVO_1495 to HVO_1499, encoding homologues of the five bacterial phosphotransferase system (PTS) components enzyme IIB (EIIB), enzyme I (EI), histidine protein (HPr), EIIA, and EIIC, is highly upregulated as a cotranscript
in the absence of glucose, ptsG expression is repressed by Mlc
-
in the presence of glucose, Mlc is sequestered by the dephosphorylated transporter EIICBGlc, which leads to an enhanced ptsG transcription
-
ptsG expression is regulated in multiple ways, overview
