CC -!- FUNCTION: One of the proteins required for the normal export of
CC preproteins out of the cell cytoplasm. It is a molecular chaperone that
CC binds to a subset of precursor proteins, maintaining them in a
CC translocation-competent state. It also specifically binds to its
CC receptor SecA. {ECO:0000255|HAMAP-Rule:MF_00821}.
CC -!- SUBUNIT: Homotetramer, a dimer of dimers. One homotetramer interacts
CC with 1 SecA dimer. {ECO:0000255|HAMAP-Rule:MF_00821}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00821}.
CC -!- SIMILARITY: Belongs to the SecB family. {ECO:0000255|HAMAP-
CC Rule:MF_00821}.
