This entry represents a group of metalloproteases. The tertiary structure of the Escherichia coli TdlD/TdlE complex has been solved, and shows that the TdlD subunit is the active peptidase, binding a single zinc ion at an HEXXXH motif in which the glutamic acid is a substrate-binding residue and the two histidines are zinc ligands. The third zinc ligand is a cysteine, C-terminal to the HEXXXH motif. The TldE (also known as PmbA) by itself has no catalytic activity, does not bind zinc, and does not carry the HEXXXH motif [1]. TldD and TldE were originally identified as regulators of DNA gyrase. Later, they are shown to be metalloproteases involved in CcdA degradation [2-3].	Domain
