发帖数: 911 | 1 DNA topoisomerases are enzymes that catalyze the passage of individual DNA
strands or double helices through one another. These reactions are often
manifested in interconversions between topological isomers of DNA rings;
hence the name of the enzymes...
There are three enzymes in this group: E.coli DNA topoisomerase I,
mouse DNA topoisomerase I, and E.coli topoisomerase II, respectively,
representing 3 distinct subfamilies of topoisomerases.
Both E.coli DNA topoisomerase I and mouse DNA topoisom |
