Overview of RRMs in complex with 10mer RNA. a Cartoon representation of RRMs in complex with 10mer RNA 5′-AAGGACUAGC-3′. The RNA backbone is colored in yellow shown by stick. The molecule from the adjacent asymmetric unit is colored in green. b Surface representation of RRMs–10mer complex. c Intermolecular contacts between RRM1 and residues of 10mer RNA 5′-AAGG-3′, and RRM2 with residues of RNA 5′-ACUAGC-3′. d Superposition of 8mer and 10mer RNA substrates. The 8mer RNA 5′-AGGACUGC-3′ is colored in marine and the 10mer RNA 5′-AAGGACUAGC-3′ is colored in yellow
