Yeast mutants resistant to L-canavanine were selected. All were recessive and fell into the can1 complementation group. Nonsense mutations were identified among them by using a set of different suppressors. Frequencies of UAA, UAG, and presumed UGA mutations were 14.8, 0.8, and 0.4%, respectively. A high incidence of nonsense mutations having discriminatory suppression patterns was characteristic of the locus.
筛选出了对L-刀豆氨酸具有抗性的酵母突变体。所有突变体均为隐性,且都属于can1互补群。通过使用一组不同的抑制子在其中鉴定出了无义突变。UAA、UAG以及推测的UGA突变的频率分别为14.8%、0.8%和0.4%。具有鉴别性抑制模式的无义突变的高发生率是该基因座的特征。
