The true substrate for the pyruvate kinase catalyzed phosphorylation of hydroxylamine at high pH which is activated by bicarbonate is shown to be N-hydroxycarbamate, since a lag is seen when the reaction is started by the addition of bicarbonate or

Carcinogenic urethane (ethyl carbamate) forms DNA adduct via epoxide, whereas carcinogenic methyl carbamate can not. To clarify a mechanism independent of DNA adduct formation, we examined DNA damage induced by N-hydroxyurethane, a urethane metabolite, using 32P-5'-end-labeled DNA fragments. N-hydroxyurethane induced

N-Hydroxyurea and two structurally related compounds, acetohydroxamic acid and N-hydroxyurethane, were investigated for their potential to induce DNA repair synthesis in primary rat hepatocyte cultures. Repair was determined as repair replication by means of the bromodeoxyuridine density-shift method and, in
