Some of the factors that affect the intensities and the phases of the first five equatorial x-ray
reflections from skeletal muscle are studied by simplified models describing axially projected …

High resolution information about the three-dimensional (3D) structure of myosin filaments
has always been hard to obtain. Solving the 3D structure of myosin filaments is very …

Axial x-ray diffraction patterns from single intact fibers of frog skeletal muscle were recorded
by using a highly collimated x-ray beam at the European Synchrotron Radiation Facility …

X-ray scattering and diffraction from non-crystalline systems have gained renewed interest in
recent years, as focus shifts from the structural chemistry information gained by high …

The regulation of striated muscle contraction involves changes in the interactions of troponin
and tropomyosin with actin thin filaments. In resting muscle, myosin-binding sites on actin …

Small-angle scattering studies on biological structures provide low-resolution models. More
detailed models need a more elaborate analysis in order to show their uniqueness. The …

We have obtained light and X-ray diffraction patterns from trabecular and papillary muscles
of various mammalian hearts in the living resting state and in rigor. Equatorial X-ray …

The molecular mechanism of muscle contraction has been elucidated by a combination of
electron microscopy, biochemistry and X-ray diffraction from fibres and crystals. Protein …

To clarify the extensibility of thin actin and thick myosin filaments in muscle, we examined
the spacings of actin and myosin filament-based reflections in x-ray diffraction patterns at …

Low angle x-ray diffraction measurements of myofilament lattice spacing (D 1, 0) and
equatorial reflection intensity ratio (I 1, 1/I 1, 0) were made in relaxed skinned cardiac …
