Figure 5. Crystal structure of adenovirus FArdV1 Pre-pVII NLSd bound to IMPα2ΔIBB. Protein crystals of IMPα2ΔIBB in complex with FrAdV1 Pre-pVII NLSd FITC-labelled peptide were formed after 3 days of incubation at 23 0C with 0.65M Na Citrate, pH 6.5. The structure solved at 2.2 Å resolution showed the FAdV1 pVII NLSd (shown in green color stick mode) bound to IMPα (shown in grey surface mode) at the major binding site. The P2 binding pocket (pink surface) is comprised of Gly150, Thr155 and Asp192.
