Comparison of the cleavage of pyrimidine dimers by the bacteriophage T4 and Micrococcus luteus UV-specific endonucleases.
Open accessAbstract
A comparison was made of the activity of the UV-specific endonucleases of bacteriophage T4 (T4 endonuclease V) and of Micrococcus luteus on ultravilet light-irradiated DNA substrates of defined sequence. The two enzymes cleave DNA at the site of pyrimidine dimers with the same frequency. The products of the cleavage reaction are the same, suggesting that the scission of DNA by T4 endonuclease V occurs via the combined actin of a pyrimidine dimer specific DNA glycosylase and an apyrimidinic-apurinic (AP) endonuclease as was recently shown for the M. luteus enzyme. The pyrimidine dimer DNA-glycosylase activity of both enzymes is more active on double-stranded DNA than it is on single-stranded DNA.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
