CC   -!- FUNCTION: Makes mgtA transcription sensitive to intracellular proline
CC       levels. Under low levels of proline this protein cannot be fully
CC       translated, and a stem loop forms which permits transcription of the
CC       downstream mgtA gene (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the MgtL family. {ECO:0000305}.
