Crystal growth has become a major bottleneck in further development of protein crystallography. One promising area of research is protein crystal growth in the microgravity environment of space. A series of growth experiments were performed on U.S. shuttle flight STS-26 in September, 1988 and STS-29 in March, 1989. For those proteins which produced crystals of adequate size, three-dimensional intensity data sets with electronic area detector systems were collected. Comparisons of the microgravity-grown crystals with the best earth-grown crystals demonstrate that the microgravity-grown crystals are larger, display more uniform morphologies, and yield diffraction data to significantly higher resolutions.
