The GHKL domain (Gyrase, Hsp90, Histidine Kinase, MutL) is an evolutionary conserved protein domain.[2] It is an ATPase domain found in several ATP-binding proteins such as histidine kinase, DNA gyrase B, topoisomerases,[3] heat shock protein HSP90,[4][5][6] phytochrome-like ATPases and DNA mismatch repair proteins.
