Biochemical Properties of Unusual Polyamines Found in an Extreme Thermophile, Thermus thermophilus
An extreme thermophile, Thermus thermophilus was isolated from a Japanese hot spring (Oshima and Imahori, 1974) which can grow in a temperature range of 50 °C to 85 °C. This unique microorganism produces a variety of polyamines. So far thirteen polyamines and two diamines have been detected; their trivial names and chemical structures are listed in Table 1. Most of these polyamines have been extracted from the thermophile, purified and identified by NMR, mass, and IR spectra. Their identification was finally confirmed by chemical synthesis (Oshima, 1983A). Unusually long polyamines and branched polyamines produced by the thermophile may play important roles in the thermophile cells and may exhibit unique activities in biochemical reactions in vitro.
