摘要

A soluble human O-6-alkylguanine-DNA alkyltransferase (hAGT) chimera was engineered containing the active site of OGT (residues 139-159) and an additional S134P mutation. The resulting hAGT chimera not only retained hAGT's ability to repair bulky O-6-alkylene-2'-deoxyguanosine interstrand cross-linked DNA damage but also displayed enhanced repair of various O-4-alkyl thymidine adducts.RI Wilds, Christopher/K-4012-2013OI Wilds, Christopher/0000-0002-0336-4753
