Abstract

We have found that L-canavanine inhibited the synthesis of polyamines in T4-infected Escherichia coli. These polyamines are known to be required for T4 DNA synthesis and may be involved in phage morphogenesis. The new data indicate that the inhibition of polyamine synthesis is not primarily responsible for the L-conavanine-mediated inhibition of DNA synthesis nor does it seem to be involved in the induction of lollipops. L-Canavanine does influence the relative amounts of putrescine and spermidine found in the phage particle, but it does not influence the amount of DNA phosphate neutralized by polyamines.

摘要

我们发现L-刀豆氨酸可抑制T4噬菌体感染的大肠杆菌中多胺的合成。已知这些多胺是T4噬菌体DNA合成所必需的,并且可能参与噬菌体形态发生。新数据表明,多胺合成的抑制并非L-刀豆氨酸介导的DNA合成抑制的主要原因,也似乎不参与棒棒糖结构的诱导。L-刀豆氨酸确实会影响噬菌体颗粒中腐胺和亚精胺的相对含量,但不会影响被多胺中和的DNA磷酸盐的量。
