Protein

ATP-dependent Clp protease ATP-binding subunit ClpA

Gene

clpA

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

ATP-dependent specificity component of the ClpAP protease. It directs the protease to specific substrates. It has unfoldase activity. The primary function of the ClpA-ClpP complex appears to be the degradation of unfolded or abnormal proteins.
