Glucoamylase crystals of Monascus sp. were examined under the electron microscope after fixation with glutaraldehyde and negative staining with uranyl acetate. At low magnification (x30,000), the crystals were rod in shape with sharp edges. At high magnification (x162,000), the enzyme molecules could be visualized as spheres 50A in diameter and arranged orderly. The intermolecular spacing was about 6A. No subunit was observed.Selected area electron diffraction patterns of the crystals showed four rings, with...

Glucoamylase crystals of Monascus sp. were examined under the electron microscope after fixation with glutaraldehyde and negative staining with uranyl acetate. At low magnification (x30,000), the crystals were rod in shape with sharp edges. At high magnification (x162,000), the enzyme molecules could be visualized as spheres 50A in diameter and arranged orderly. The intermolecular spacing was about 6A. No subunit was observed.Selected area electron diffraction patterns of the crystals showed four rings, with interplanar spacings d of 6.4A, 3.2A, 2.1A and 1.3A. The method of laser optical diffraction has been used to analyse the micrographs. It was proved that the crystal of glucoamylase was a true crystal ordered in three dimensions.
