CC   -!- FUNCTION: Regulates secA expression by translational coupling of the
CC       secM secA operon. Translational pausing at a specific Pro residue 5
CC       residues before the end of the protein may allow disruption of a mRNA
CC       repressor helix that normally suppresses secA translation initiation.
CC       {ECO:0000255|HAMAP-Rule:MF_01332}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000255|HAMAP-
CC       Rule:MF_01332}. Periplasm {ECO:0000255|HAMAP-Rule:MF_01332}. Note=The
CC       active form is cytosolic, while the periplasmic form is rapidly
CC       degraded, mainly by the tail-specific protease. {ECO:0000255|HAMAP-
CC       Rule:MF_01332}.
CC   -!- SIMILARITY: Belongs to the SecM family. {ECO:0000255|HAMAP-
CC       Rule:MF_01332}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAV76170.1; Type=Erroneous initiation; Evidence={ECO:0000305};
