Effects of polyamines on protein synthesis and growth of Escherichia coli

The polyamines (PA) putrescine, spermidine, and spermine have numerous roles in the growth of both prokaryotic and eukaryotic cells. For example, it is well known that putrescine and spermidine are strongly involved in proliferation and viability of Escherichia coli cells. Studies of polyamine functions and distributions in E. coli cells have revealed that polyamines mainly exist as an RNA–polyamine complex. Polyamines stimulate the assembly of...
