T1 0-109 Sentence denotes Repair of O6-methylguanine and O4-methylthymine by the human and rat O6-methylguanine-DNA methyltransferases.
T1 0-109 Sentence denotes Repair of O6-methylguanine and O4-methylthymine by the human and rat O6-methylguanine-DNA methyltransferases.
T2 110-418 Sentence denotes In order to compare the ability of the human and rat O6-methylguanine-DNA methyltransferases (transferases) to repair in vitro O6-methylguanine (O6-MeGua) and O4-methylthymine (O4-MeThy) residues, which are two mutagenic DNA adducts formed by alkylating agents, we have purified both proteins to homogeneity.

T3 419-582 Sentence denotes Gel electrophoresis of the proteins shows that the O4-MeThy repair is due to the transfer of the methyl group from the alkylated base to the transferase molecules.
T3 419-582 Sentence denotes Gel electrophoresis of the proteins shows that the O4-MeThy repair is due to the transfer of the methyl group from the alkylated base to the transferase molecules.
T4 583-788 Sentence denotes However, both proteins repair with different efficiencies the O6-MeGua and O4-MeThy residues present in alkylated DNA, poly[d(G.C)], poly(dG.dC), or in alkylated poly[d(A.T)] and poly(dA.dT), respectively.
