title: Genetic mapping of nth, a gene affecting endonuclease III (thymine glycol-DNA glycosylase) in Escherichia coli K-12.
abstract: The nth gene of Escherichia coli affects the production of endonuclease III, a glycosylase-endonuclease that attacks DNA damaged by oxidizing agents or by ionizing radiation. An nth insertion mutant and a deletion mutant were studied. nth is located between add and tyrS on the linkage map of E. coli K-12 and was 97% linked to tyrS in a transduction with phage P1.
