  • PubMed Abstract: 

    A crystal structure of lysozyme in complex with p-sulfonato-calix[4]arene (sclx4) reveals a linear assembly of protein tetramers glued together by protein-calixarene interactions. One interaction involves encapsulation of the highly exposed C-terminal Arg128. The other involves an intricate protein-bound complex of sclx4, Mg(2+) and a fragment of polyethylene glycol.
