The new enzyme, called topoisomerase V, has the following properties in common with eukaryotic topoisomerase I, which distinguish it from all other known prokaryotic topoisomerases: (1) its activity is Mg(2+)-independent; (2) it relaxes both negatively and positively supercoiled DNA; (3) it makes a covalent complex with the 3' end of the broken DNA strand; and (4) it is recognized by antibody raised against human topoisomerase I. Eukaryotic-like enzymes have been discovered in some hyperthermophilic prokaryotes, namely the eocytes and the extremely thermophilic archaebacteria, and hyperthermophilic homologues of eukaryotic DNA polymerase-alpha, transcription factor IIB and DNA ligase have all been reported.
