Protein attributes

Sequence length	162 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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.
