摘要：

We have verified the report that Pseudomonas (Kim) contains no spermidine, but have found that this strain contains another polyamine, 2-hydroxyputrescine, previously unidentified in bacteria. As in Escherichia coli the concentration of magnesium in the S-100 fraction is the same as the extracellular concentration. Unlike Escherichia coli both ribosome-bound putrescine and ribosome-bound hydroxyputrescine vary inversely with extracellular concentration of magnesium, but the behavior of bound hydroxyputrescine in Pseudomonas (Kim) resembles that of bound spermidine in Escherichia coli. © 1969.
