Abstract

Cellular polyamines of newly isolated acidophilic, thermophilic and thermoacidophilic archaebacteria were investigated for the chemotaxonomic significance of polyamine distribution profiles. In addition to spermidine, spermine and agmatine, a quaternary branched penta-amine, N(4)-bis(aminopropyl)spermidine, was found in thermophilic Thermococcus waiotapuensis, Thermococcus aegaeus and Pyrococcus glycovorans belonging to the order Thermococcales. An acidophilic euryarchaeon, Ferroplasma acidiphilum located in the order Thermoplasmatales, contained spermidine and agmatine. Norspermidine, spermidine, norspermine and spermine were found in thermoacidophilic Acidilobus aceticus and thermophilic Thermodiscus maritimus located in the order Desulfurococcales, and in thermophilic Pyrobaculum arsenaticum, Pyrobaculum oguniense, Vulcanisaeta distributa and Vulcanisaeta souniana belonging to the order Thermoproteales; however, the four genera differ on their tetra- and penta-amine levels. Thermophilic Staphylothermus hellenicus belonging to Desulfurococcales contained caldopentamine, caldohexamine and N1-acetylcaldopentamine in addition to norspermidine, spermidine and norspermine. This is the first report on the occurrence of acetylated penta-amine in nature.
