Comments [?]

FUNCTIONTopoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule.
CATALYTIC ACTIVITY Reaction=ATP-dependent breakage, passage and rejoining of double- stranded DNA.; EC=5.6.2.2;
SUBUNITHeterotetramer composed of ParC and ParE.
SUBCELLULAR LOCATIONCell membrane; Peripheral membrane protein.
SIMILARITYBelongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
