Summary
ClpP can simultaneously bind ClpX and ClpA to form a heteromeric complex. [More information is available at EcoGene: EG10158]. ClpP is a serine protease with a chymotrypsin-like activity that is a part of the ClpAP, ClpAPX and ClpXP protease complexes . [More information is available at EcoCyc: EG10158].
