Abstract

Pseudomonas sp. strain Kim has previously been reported to be the only known naturally occurring organism lacking spermidine. We now show that it synthesizes this polyamine. The apparent lack of intracellular levels of spermidine results from an efficient conversion of spermidine to putrescine and hydroxyputrescine.
