About this Structure
1QOY is a monomer from the dodecameric pore-forming toxin from Escherichia coli. Though its crystal structure, 2WCD (shown above, rendered in Pymol) revealed a dodecamer, larger pores have been isolated, as well.
Research on ClyA at UMass Amherst
The Chen Lab, in collaboration with the Heuck lab, recently published a paper on ClyA assembly.
