Abstract
Bacteriophage phi W-14 is sensitive to osmotic shock. It contain sufficient free putrescine, 2-hydroxyputrescine and spermidine to neutralize about 15% of the DNA phosphates. The alpha-putrescinylthymine residues of the DNA could neutralize a further 25% of the phosphates. Label is transferred from ornithine to the alpha-putrescinyl residues of phi W-14 DNA. The rates of polyamine synthesis in Pseudomonas acidovorans are increased by phi W-14 infection.
摘要
噬菌体phi W-14对渗透压休克敏感。它含有足够的游离腐胺、2-羟基腐胺和亚精胺来中和约15%的DNA磷酸盐。DNA的α-腐胺基胸腺嘧啶残基可进一步中和25%的磷酸盐。标记从鸟氨酸转移到phi W-14 DNA的α-腐胺基残基上。phi W-14感染会提高食酸假单胞菌中多胺的合成速率。
