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}.
