>TIGR00382 clpX ATP-dependent Clp protease, ATP-binding subunit ClpX; InterPro: IPR004487 ClpX is a member of the HSP (heat-shock protein) 100 family. Gel filtration and electron microscopy showed that ClpX subunits associate to form a six-membered ring that is stabilized by binding of ATP or nonhydrolyzable analogs of ATP . It functions as an ATP-depedent molecular chaperone and is the regulatory subunit of the ClpXP protease . ClpXP is involved in DNA damage repair, stationary-phase gene expression, and ssrA-mediated protein quality control. To date more than 50 proteins include transcription factors, metabolic enzymes, and proteins involved in the starvation and oxidative stress responses have been identified as substrates . The N-terminal domain of ClpX is a C4-type zinc binding domain (ZBD) involved in substrate recognition. ZBD forms a very stable dimer that is essential for promoting the degradation of some typical ClpXP substrates such as lO and MuA . ; GO: 0005515 protein binding, 0005524 ATP binding, 0016887 ATPase activity, 0015031 protein transport.
