By making use of the gam(+)-plasmid, the so-called gam-dependent radioresistance was studied. This resistance is the result of the interaction between Gam protein (encoded by the gam gene of lambda) and RecBCD enzyme of Escherichia coli. gam-dependent radioresistance is observed in recB+ recC+ recD+ but not in recB+ recC+ recD- cells. It is suggested that Gam protein interacts specifically with the RecD subunit of RecBCD enzyme; the RecBC complex probably retains its activity in the presence of this viral protein.
通过利用gam(+)质粒，对所谓的gam依赖性辐射抗性进行了研究。这种抗性是Gam蛋白（由λ噬菌体的gam基因编码）与大肠杆菌的RecBCD酶相互作用的结果。在recB+ recC+ recD+细胞中观察到gam依赖性辐射抗性，而在recB+ recC+ recD-细胞中未观察到。有人认为，Gam蛋白与RecBCD酶的RecD亚基特异性相互作用；在这种病毒蛋白存在的情况下，RecBC复合物可能保留其活性。
