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.
一方面,噬菌体T3与另一方面的T3sam - 和T7之间的某些差异表明,T3编码的S-腺苷甲硫氨酸酶(SAMase)功能负责:(i)通过防止T3 DNA甲基化来形成假溶原状态;(ii)对噬菌体DNA提供部分保护,使其免受P系统的限制。
