GlcT is a transcriptional antiterminator protein that is involved in regulation of glucose metabolism in Bacillus subtilis. Antiterminator proteins bind specific RNA sequences, thus preventing the formation of overlapping terminator stem-loops. The structure of a fragment (residues 3-170) comprising the RNA-binding domain (RBD) and the first regulatory domain (PRDI) of GlcT was solved at 2.0 A resolution with one molecule in the asymmetric unit. The two domains are connected by a helical linker. Their interface is mostly constituted by hydrophobic interactions.

Function

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.[1] [2]
