In E. coli Clp protease, ser-111, his-136 and asp-185 form the catalytic triad. Swiss:P48254 has lost all of these active site residues and is therefore inactive. Swiss:P42379 contains two large insertions, Swiss:P42380 contains one large insertion.

PF10431C-terminal, D2-small domain, of ClpB protein (ClpB_D2-small)C-terminal, D2-small domain, of ClpB proteinThis is the C-terminal domain of ClpB protein, referred to as the D2-small domain, and is a mixed alpha-beta structure.

Compared with the D1-small domain (included in AAA, Pfam:PF00004) it lacks the long coiled-coil insertion, and instead of helix C4 contains a beta-strand (e3) that is part of a three stranded beta-pleated sheet. In Thermophilus the whole protein forms a hexamer with the D1-small and D2-small domains located on the outside of the hexamer, with the long coiled-coil being exposed on the surface. The D2-small domain is essential for oligomerisation, forming a tight interface with the D2-large domain of a neighbouring subunit and thereby providing enough binding energy to stabilise the functional assembly [1]. The domain is associated with two Clp_N, Pfam:PF02861, at the N-terminus as well as AAA, Pfam:PF00004 and AAA_2, Pfam:PF07724.
