Yeast strains carrying SUP4-o genes that have base-pair substitutions at hotspots for UV or MNNG mutagenesis were treated with these agents. In both cases, the induced mutation frequencies were substantially reduced. Furthermore, specific substitutions at positions in SUP4-o that had not been mutated by MNNG resulted in the recovery of MNNG-induced mutations at these sites. These results demonstrate that base-pair identity is an important factor determining the site-specific mutagenicity of UV and MNNG in yeast. For UV, our findings suggest that the type of lesion that is induced, but not flanking DNA sequences, plays a role in specifying mutability at the sites examined. In contrast, DNA sequence context seems to be an important factor for MNNG mutagenesis.
