title: [Determination of the molecular weight and form of the molecule histidine decarboxylase by the method of small-angle x-ray scattering].
abstract: Shape and molecular weight of histidine-decarboxylase from Micrococus sp. n. were studied by the method of X-ray small-angle scattering. The inertion radius of the molecule: Rg-2,93 nm. The shape of the molecule is adequately approximated by rotation ellipsoids of two possible variants: the elongated and flattened ones. The eccentricity in both cases is 1.6. The volume of the enzyme molecule V=190 nm3. The molecular weight of histidine-dexarboxilase obtained from the X-ray experiment M=102 000 c.u.
