1XWP, 1XWU - PubMed Abstract: 
A high affinity RNA aptamer (APT58, 58 nt long) against mammalian initiation factor 4A (eIF4A) requires nearly its entire nucleotide sequence for efficient binding. Since splitting either APT58 or eIF4A into two domains diminishes the affinity for each other, it is suggested that multiple interactions or a global interaction between the two molecules accounts for the high affinity ...
