title: Inducible DNA repair enzymes involved in the adaptive response to alkylating agents.
abstract: Two different DNA repair enzymes are induced in E. coli by methylating agents: a methyltransferase acting on 0(6)-methylguanine residues, and a DNA glycosylate for N-methylated purines. The properties of the homogeneous methyltransferase are described.
