Bacteriorhodopsin crystal growth under microgravity--results of IML-1 and Spacehab-1 experiments.
The results of two crystal-growth experiments in microgravity with the membrane protein bacteriorhodopsin are reported, namely the IML-1 experiment in the Advanced Cryostat which resulted in a significant improvement in the compact crystal morphology of the needles, and the Spacehab-1 experiment in the Advanced Protein Crystallisation Facility which extended the IML-1 results with improved morphology of the triclinic needles. The enhanced diffractional power of these bacteriorhodopsin crystals grown in microgravity has extended the hitherto 8 angstroms resolution limit by 2 angstroms.
