嗜热菌是一种极端嗜热菌，属于领域细菌，除了标准多胺外，还会产生不寻常的多胺。为了解嗜热菌多胺组成随环境温度等生长条件变化的机理，对嗜热T菌多胺生物合成代谢途径进行了研究，提出了一种新的多胺代谢途径。然而，许多谜团仍有待于未来的研究解开。本文讨论了在植物细胞中也产生并发挥重要作用的两种非标准多胺--热敏胺和均高胺的生物合成与植物体内生物合成反应的关系。(C)2010年爱思唯尔·马森公司。版权所有,
Thermus thermophilus, an extreme thermophile belonging to Domain Bacteria, produces unusual polyamines in addition to standard polyamines. To understand mechanisms of changes of polyamine compositions of the thermophile upon change of growth conditions such as environmental temperature, metabolic pathways of polyamine biosyntheses of T thermophilus have been studied and a new polyamine metabolic pathway was proposed. However, many enigmas remain to be solved in future studies. In this paper, biosyntheses of two non-standard polyamines, thermospermine and sym-homospermidine which are also produced and play important roles in plant cells, of the extreme thermophile are discussed in relation to the biosynthetic reactions in plants.
