CONCLUSION
In this paper, three types of UV endonucleases(UV endonucleases I, II and III) were
identified from human fibroblasts which appear to be homologues of the murine
enzymes. UV endonucleases III from murine plasmacytoma cells or human fibroblasts
are similar in chromatographic and catalytic properties. UV endonuclease III also cleaves
DNA containing thymine glycol. UV endonuclease III appears to be a versatile enzyme
becaure it recognizes and cleaves AP site containing DNA, pyrimidine dimer containing
DNA and thymine glycol containing DNA. All these base damages are believed to be
mutagenic to cells and possibly causing cancers. Therefore, it is plausible that lacking of
UV endonuclease III in XP-D cells is directly related to the generation of skin cancers.
