Protein-export protein SecB

Gene

secB

Organism
Rhodopseudomonas palustris (strain HaA2)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation
