Protein attributes
| Sequence length | 152 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| 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. |
| Subunit structure | Homotetramer, a dimer of dimers. One homotetramer interacts with 1 secA dimer By similarity. |
| Subcellular location | Cytoplasm By similarity. |
| Sequence similarities | Belongs to the secB family. |
