High impact information on Gstt1

  • The four DNA nucleosides were also reacted with the dihalomethanes CH(2)Cl(2) and CH(2)Br(2) in the presence of glutathione (GSH) and GSH S-transferases from bacteria (DM11), rat (GST 5-5), and human (GST T1-1) under conditions that produce mutations in bacteria [1].
  • We examined rat GST 5-5 and human GST T1-1 and did not detect any burst kinetics in the conjugation of C(2)H(5)Cl, CH(2)Br(2), or CH(2)Cl(2), distinguishing these enzymes from GST DM11 [2].
  • 1,2-Epoxy-3-(4'-nitrophenoxy)propane and 2,3-dibromo-1-chloropropane were inactivated by GST 5-5 in the NM5004 tester strain, although these chemicals were cytotoxic in both tester strains [3].
  • Roles of GST 5-5 were also examined for the inactivation of reactive metabolites of several procarcinogens that were formed through oxidation by liver microsomes of polychlorinated biphenyl-treated rats [3].
  • Dichloromethane mediated in vivo selection and functional characterization of rat glutathione S-transferase theta 1-1 variants [4].
