Protein
PtsGHI operon antiterminator
Organism
Bacillus subtilis (strain 168)
Function
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.
Similarity
Belongs to the transcriptional antiterminator BglG family. GlcT subfamily.
