* '''Catalyzed reaction/ biological activity:''' transport and phosphorylation of glucose, receives a phosphate from [[PtsH |HPr]] at the IIA domain (His-620), the phosphate group is then transferred to the IIB domain (Cys-461) an finally to the incoming glucose. In the absence of glucose, PtsG phosphorylates and thereby inactivates the transcriptional antiterminator [[GlcT]].
