Enzyme Information

5.6.2.3
DNA topoisomerase (ATP-hydrolyzing).
based on mapping to UniProt P0AES5
ATP-dependent breakage, passage and rejoining of double-stranded DNA.
-!- The enzyme can introduce negative superhelical turns into double- stranded circular DNA. -!- One unit has nicking-closing activity, and another catalyzes super- twisting and hydrolysis of ATP (cf. EC 5.6.2.2). -!- Formerly EC 5.99.1.3.
