Name ClpX zinc binding (ZB) domain
Function ClpX consists of an NH(2)-terminal zinc binding (ZB) domain that is involved in substrate and cofactor recognition and a AAA(+) domain that arranges into a hexamer in an ATP-dependent manner. The ClpX ZB domain contains the characteristic pattern C-X(2)-C-X(18)-C-X(2)-C of four cysteine residues and forms a constitutive dimer that is essential for the degradation of some ClpX substrates such as lambdaO and MuA but is not required for the degradation of other substrates such as green fluorescent protein SsrA.
Scope(s) Bacteria
Example(s) Q6G177 (CLPX_BARQU);
