[[http://www.uniprot.org/uniprot/GLCT_BACSU GLCT_BACSU]] Mediates the positive regulation of the glucose PTS operon (ptsGHI) by functioning as an antiterminator factor of transcription via its interaction with the RNA-antiterminator (RAT) sequence located upstream of the ptsG gene. The RNA-binding domain of GlcT directly binds to the RNA antiterminator (RAT) sequence and prevents transcriptional termination. GlcT binding requires two identical and nearly symmetrical triple base pairings in the RAT sequence.<ref>PMID:11902727</ref> <ref>PMID:9765562</ref>
