In situ atomic force microscopy was utilized to study the relation between crystal structure, surface morphology, and growth mechanisms of faces of macromolecular crystals that have screw axes perpendicular to them. It was found that the {001} faces of orthorhombic catalase, trigonal trypsin, and tetragonal Bence-Jones protein (BJP) crystals grow by successive deposition of n alternating, symmetry-related...
