| 3.2.2.17 | DNA + H2O |
the combined rate of sugar ring opening and reduction of the sugar is significantly slower than the rate of formation of (T4-pdg)-DNA intermediate |

| 3.2.2.17 | DNA + H2O |
the enzyme incises DNA at cyclobutane pyrimidine dimers that are formed as a consequence of exposure to ultraviolet light. The investigation reveals a temporal uncoupling of the T4-Pdg-induced DNA bending and nucleotide flipping |

3'nicking is not result of the hydrolysis of the phospho ester bond, but rather result of a beta-elimination reaction, the sequence of the 138 amino acid residues of T4 UV endonuclease is known, active sites for DNA glycosylase and the nicking activity seem to be independent, since endonuclease is a phosphoric diester hydrolase classified as EC 3.1.4.-T4 UV endonuclease and Micrococcus luteus endonuclease are not endonucleases |
