General annotation (Comments)

Function

One of the proteins required for the normal export of preproteins out of the cell cytoplasm. It is a molecular chaperone that binds to a subset of precursor proteins, maintaining them in a translocation-competent state. It also specifically binds to its receptor secA By similarity. HAMAP MF_00821

Subunit structure

Homotetramer, a dimer of dimers. One homotetramer interacts with 1 secA dimer By similarity.

Subcellular location

Cytoplasm By similarity HAMAP MF_00821.

Sequence similarities

Belongs to the secB family.
