CC   -!- FUNCTION: Activates the small RNA gene sgrS under glucose-phosphate
CC       stress conditions as well as yfdZ. Represses its own transcription
CC       under both stress and non-stress conditions. Might act as a sensor of
CC       the intracellular accumulation of phosphoglucose by binding these
CC       molecules in its C-terminal solute-binding domain. {ECO:0000255|HAMAP-
CC       Rule:MF_01449}.
