Distribution of biogenic amines—the diamine putrescine (Put), triamine spermidine (Spd), and tetraamine spermine (Spm)—differs… Expand Summary.The naturally occurring polyamines, spermine, spermidine and the diamine putrescine are widespread in nature. They have… Expand The diamine putrescine and the polyamines spermidine and spermine are found in a wide range of organisms from bacteria to plants… Expand The natural polyamines putrescine, cadaverine, spermidine, and spermine are found in all cells. These (poly)cations exert… Expand Four cDNAs for spermidine synthase (SPDS), which converts the diamine putrescine to the higher polyamine spermidine using… Expand The polyamines putrescine, spermidine and spermine are essential for cell renewal and, therefore, are needed to keep the body… Expand The diamine putrescine, the triamine spermidine, and the tetramine spermine are ubiquitous in plant cells, while other polyamines… Expand The effect of D,L-alpha-difluoromethylornithine (DFMO) on thiol and polyamine levels in Trypanosoma brucei was investigated by… Expand Since the diamine putrescine can be metabolized into the pyrrolidine ring of tobacco alkaloids as well as into the higher… Expand The biochemistry and biological function of the naturally occurring polyamines, putrescine, spermidine, and spermine, have been… Expand
