Abstract
sym-Homospermidine (HSpe) was compared with its structural isomer, aminopropylcadaverine (AP5), and the naturally-occurring triamine, spermidine (Spe), in its ability to stimulate the growth of Spe auxotrophs of Escherichia coli. HSpe was taken up by the cells, but was less effective than Spe in stimulating growth. In at least one E. coli auxotroph, HSpe was also less effective than AP5.
摘要
将对称高亚精胺（HSpe）与其结构异构体氨丙基尸胺（AP5）以及天然存在的三胺亚精胺（Spe）在刺激大肠杆菌Spe营养缺陷型菌株生长的能力方面进行了比较。HSpe被细胞摄取，但在刺激生长方面不如Spe有效。在至少一种大肠杆菌营养缺陷型菌株中，HSpe也不如AP5有效。
