Complementary functions of the Saccharomyces cerevisiae Rad2 family nucleases in Okazaki fragment maturation, mutation avoidance, and chromosome stability.

Abstract excerpt

Rad2 family nucleases, identified by sequence similarity within their catalytic domains, function in multiple pathways of DNA metabolism. Three members of the Saccharomyces cerevisiae Rad2 family, Rad2, Rad27, and exonuclease 1 (Exo1), exhibit both 5' exonuclease and flap endonuclease activities. Deletion of RAD27 results in defective Okazaki fragment maturation, DNA repair, and subsequent defects in mutation...
