Spermidine-Deoxyribonucleic acid interaction in vitro and in Escherichia coli.
The binding of spermidine to deoxyribonucleic acid (DNA) was studied by equilibrium dialysis in a wide range of salt concentrations. The association constants ranged from 6 x 10(5) M-1 in 1 mM sodium cacodylate, pH 7.5, to 3 x 10(2) M-1 in 0.3 M NaCl. MgCl2 reduced spermidine-DNA interaction even mo...
