ABSTRACT

On the basis of electron microscope data the structure of tubular crystals of catalase has been determined with resolution of approximately 25 A. The symmetry of the helical packing of molecules is 142/17. The three-dimensional reconstruction has been carried out in real space. The catalase molecule consists of four subunits whose centers from a fairly flattened tetrahedron. The molecule has dimensions of 69X87X92 A.
