title: A new naturally occurring polyamine containing a quaternary ammonium nitrogen.
abstract: A new polyamine, tetrakis(3-aminopropyl)ammonium, N+ (CH2CH2CH2NH2)4, was identified in cells of an extreme thermophile, Thermus thermophilus. This compound was chemically synthesized and its chemical properties were coincident with those of the amine isolated from the thermophile.
