Type II Topoisomerase

Type II Topoisomerase

Type II topoisomerases cut both strands of the DNA helix simultaneously in order to manage DNA tangles and supercoils. They use the hydrolysis of ATP, unlike Type I topoisomerase. In this process, these enzymes change the linking number of circular DNA by ±2.

Famous quotes containing the word type:

    They had supposed their formula was fixed.
    They had obeyed instructions to devise
    A type of cold, a type of hooded gaze.
    But when the Negroes came they were perplexed.
    These Negroes looked like men....
    Gwendolyn Brooks (b. 1917)
