Enzyme Information
| 5.6.2.3 | DNA topoisomerase (ATP-hydrolyzing). based on mapping to UniProt P0AES4 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. |
