Abstract

.beta.-Glucuronidase [EC 3.2.1.31] from rat preputial glands was crystallized as thin sheets having p6 symmetry in projection with a = 20.2 nm. A filtered image was produced by Fourier methods to a resolution of 2.2 nm by averaging information from 6 areas. This suggests an approximately triangular molecular outline in projection, and this indicates a probable tetrahedral arrangement of the 4 subunits of the .beta.-glucuronidase molecule.
