Sci Rep . 2024 Mar; 14(1):7566. PMID: 38555406
An extreme thermophilic bacterium, Thermus thermophilus produces more than 20 unusual polyamines, but their biosynthetic pathways, including homospermidine, are not yet fully understood. Two types of homospermidine synthases have been...

Kobayashi T, Sakamoto A, Kashiwagi K, Igarashi K, Takao K, Uemura T, et al.
J Biochem . 2023 Mar; 174(1):81-88. PMID: 37001547
In the three domains of life, three biosynthetic pathways are known for putrescine. The first route is conversion of ornithine to putrescine by ornithine decarboxylase (ODC: SpeC), the second route...
