Comparison of the different β-hairpin conformations. The structure of ctPrp16 was superposed with different spliceosomal DEAH-box helicases from C. thermophilum in different catalytic states via their RecA1 domains. The different β-hairpins are represented in cartoon mode, while the remaining part of the protein is shown as a gray surface (ctPrp16–ADP only). Parts of the OB-fold domain were omitted for clarity. The superposition reveals that the β-hairpin of ctPrp16–ADP adapts a more distant conformation compared with the other structures. |
