The polyamines bind to the spe2 UTR RNA. (A) Change in SPR signal in response units (RU) on Spd bound to immobilized spe2 UTR RNA. Hill coefficient is shown. (B) Change in SPR signal in RU on Spm bound to immobilized spe2 UTR RNA. Hill coefficient is shown. (C) The relationship between polyamine structure, binding affinity, and reporter gene induction. NB represents no binding.
