The major DNA excision repair pathways of base excision repair for endogenous DNA lesions and nucleotide excision repair for DNA damage inflicted by ultraviolet light have been reconstructed with purified mammalian proteins and details of these repair mechanisms are emerging. Similar data are becoming available with regard to mismatch repair for correction of replication errors. Deletion of individual DNA repair proteins in knockout mice provides information on the roles of such factors in vivo and recent three-dimensional structures of several repair enzymes explain their detailed modes of action.
