In Haemophilus influenzae strains only the type 1 of the restriction endonucleases have an in vivo effect on phage and bacterial transforming DNA. The type 2 of restriction endonucleases which act very efficiently in vitro are completely inactive in vivo. The reasons for this inactivity is unknown.
在流感嗜血杆菌菌株中，只有1型限制性内切酶对噬菌体和细菌转化DNA具有体内效应。在体外高效作用的2型限制性内切酶在体内完全无活性。这种无活性的原因尚不清楚。
