CC -!- FUNCTION: DNA-binding protein that represses the expression of many
CC genes that are induced as cells make the transition from rapid
CC exponential growth to stationary phase. It is a GTP-binding protein
CC that senses the intracellular GTP concentration as an indicator of
CC nutritional limitations. At low GTP concentration it no longer binds
CC GTP and stop to act as a transcriptional repressor. {ECO:0000255|HAMAP-
CC Rule:MF_00621}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00621}.
CC -!- SIMILARITY: Belongs to the CodY family. {ECO:0000255|HAMAP-
CC Rule:MF_00621}.
