Protein translocase subunit SecA

Gene

secA

Organism
Rickettsia bellii (strain OSU 85-389)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.UniRule annotation
