Add to ORKGThe polyamine spermidine and the diamine putrescine have been detected in coliphages T5 and ¢XI74. Polyamines were identified by thin-layer chromatography and mass-spectrometry of dansyl derivatives, as well as by ion-exchange chromato-graphy. In ¢XI74 phages, polyamines were sufficient o neutralize 0"5 ~ of DNA phosphates. The polyamine content of T5 phages depended on growth media and purification procedures, but at least I ~ of DNA phosphates were neutralized by polyamines. After infection, an increase in cellular polyamine was noticed. This increase paralleled variations in ornithine decarboxylase activity
