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.
假单胞菌属菌株Kim此前被报道为唯一已知的天然缺乏亚精胺的生物体。我们现在表明它能合成这种多胺。细胞内亚精胺水平明显缺乏是由于亚精胺有效地转化为腐胺和羟基腐胺所致。
