摘要：Ultraviolet (UV)-induced unscheduled DNA synthesis of xeroderma pigmentosum cells, belonging to complementation groups A, B, C, D, and E, was restored to the normal level by concomitant treatment of the cells with T4 endonuclease V and UV-inactivated HVJ (Sendai virus). The present results suggest that (1) T4 endonuclease molecules were inserted effectively into the cells by the interaction of HVJ with the cell membranes, (2) the enzyme was functional on human chromosomal DNA which had been damaged by UV irradiation in the viable cells, (3) all the studied groups of xeroderma pigmentosum ("variant" was not tested) were defective in the first step (incision) of excision repair.
