Crystal structure of Leishmania mexicana pyruvate kinase (LmPYK)in complex with 1,3,6,8-pyrenetetrasulfonic acidCrystal structure of Leishmania mexicana pyruvate kinase (LmPYK)in complex with 1,3,6,8-pyrenetetrasulfonic acid

Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe inclusion of novel small molecules in crystallization experiments has provided very encouraging results and this method is now emerging as a promising alternative strategy for crystallizing 'problematic' biological macromolecules. These small molecules have the ability to promote lattice formation through stabilizing intermolecular interactions in protein crystals. Here, the use of 1,3,6,8-pyrenetetrasulfonic acid (PTS), which provides a helpful intermolecular bridge between Leishmania mexicana PYK (LmPYK) macromolecules in the crystal, is reported, resulting in the rapid formation of a more stable crystal lattice at neutral pH and greatly improved X-ray diffraction results. The refined structure of the LmPYK-PTS complex revealed the negatively charged PTS molecule to be stacked between positively charged (surface-exposed) arginine side chains from neighbouring LmPYK molecules in the crystal lattice. An improved strategy for the crystallization of Leishmania mexicana pyruvate kinase.,Morgan HP, McNae IW, Hsin KY, Michels PA, Fothergill-Gilmore LA, Walkinshaw MD Acta Crystallogr Sect F Struct Biol Cryst Commun. 2010 Mar 1;66(Pt, 3):215-8.
