    CRYSTAL GROWTH & DESIGN 2001 VOL. 1, NO. 1 87-99 Review Microgravity and Macromolecular Crystallography Craig E. Kundrot,* Russell A. Judge, Marc L. Pusey, and Edward H. Snell Mail Code SD48 Biotechnology Science Group, NASA Marshall Space Flight Center, Huntsville, Alabama 35812 Received August 24, 2000 ABSTRACT: Macromolecular crystal growth is seen as an ideal experiment to make use of the reduced acceleration environment provided by an orbiting spacecraft. The experiments are small, are simply operated, and have a high potential scientific and economic impact. In this review we examine the theoretical reasons why microgravity is a beneficial environment for crystal growth and survey the history of experiments on the Space Shuttle Orbiter, on unmanned spacecraft, and on the Mir space station. The results of microgravity crystal growth are considerable when one realizes that the comparisons are always between few microgravity-based experiments and a large number of earth-based experiments. Finally, we outline the direction for optimizing the future use of orbiting platforms. 1. Introduction molecules, including viruses, proteins, DNA, RNA, and complexes of those molecules.

  • How to Make Tubular Crystals by Reconstitution of Detergent-Solubilized Ca2+-Atpase
    Biophysical Journal Volume 72 June 1997 2545-2558 2545 How to Make Tubular Crystals by Reconstitution of Detergent-Solubilized Ca2+-ATPase Howard S. Young,* Jean-Louis Rigaud,# Jean-Jacques Lacapere,# Laxma G. Reddy,§ and David L. Stokes* *Skirball Institute of Biomolecular Medicine, New York University Medical Center, New York, New York 10016 USA; #Institut Curie, Section de recherche, UMR-CNRS 168 and LCR-CEA 8, 75231 Paris, France; and §Department of Biochemistry, University of Minnesota, Minneapolis, Minnesota 55455 USA ABSTRACT In an attempt to better define the parameters governing reconstitution and two-dimensional crystallization of membrane proteins, we have studied Ca2+-ATPase from rabbit sarcoplasmic reticulum. This ion pump forms vanadate- induced crystals in its native membrane and has previously been reconstituted at high lipid-to-protein ratios for functional studies. We have characterized the reconstitution of purified Ca2+-ATPase at low lipid-to-protein ratios and discovered procedures that produce long, tubular crystals suitable for helical reconstruction. C12E8 (n-dodecyl-octaethylene-glycol monoether) was used to fully solubilize various mixtures of lipid and purified Ca2+-ATPase, and BioBeads were then used to remove the C12E8. Slow removal resulted in two populations of vesicles, and the proteoliposome population was separated from the liposome population on a sucrose density gradient. These proteoliposomes had a lipid-to-protein ratio of 1:2, and virtually 100% of molecules faced the outside of vesicles, as determined by fluorescein isothiocyanate labeling. Cycles of freeze-thaw caused considerable aggregation of these proteoliposomes, and, if phosphatidyl ethanolamine and phosphatidic acid were included, or if the bilayers were doped with small amounts of C12E8, vanadate-induced tubular crystals grew from the aggregates.
