Biological functions of the bacteriophage T3 SAMase gene.
Certain differences between phage T3 on the one hand and T3sam- and T7 on the other hand indicate that the T3-coded SAMase function is responsible (i) for the development of the pseudolysogenic state by preventing T3 DNA methylation, and (ii) for the partial protection of the phage DNA against restriction by the P system.
