CC   -!- FUNCTION: Regulatory protein for the glycine cleavage system operon
CC       (gcv). Mediates activation of gcv by glycine and repression by purines.
CC       GcvA is negatively autoregulated. Binds to three sites upstream of the
CC       gcv promoter (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the LysR transcriptional regulatory family.
CC       {ECO:0000305}.
