Protein Yoga: Conformational Versatility of the Hemolysin II C-terminal Domain Detailed by NMR Structures for Multiple States

Protein Yoga: Conformational Versatility of the Hemolysin II C-terminal Domain Detailed by NMR Structures for Multiple States

The C-terminal domain of Bacillus cereus hemolysin II, HlyIIC, stabilizes the trans-membrane-pore formed by the HlyII toxin and may aid in target cell recognition. Initial efforts to determine the NMR structure of HlyIIC were hampered by cis/trans isomerization about the single proline at position 405, that leads to doubling of NMR resonances. We used the mutant P405M-HlyIIC that eliminates the cis proline to determine the NMR structure of the domain, which revealed a novel fold. Here, we extend...
