At present researchers usually rely on X-ray crystallography to investigate protein structures. This requires growing crystals consisting of billions of identical molecules.
The researchers used X-ray crystallography and Raman scattering spectroscopy to ensure they had produced the crystal structure and symmetry they intended.

You could call it crystal-free crystallography, says Jon Clardy, a biological chemist at Harvard Medical school in Boston,
X-ray crystallography is one of the most important techniques in science, because it is one of only a few ways to directly determine the shape of large molecules.
Clardy says, the biggest bottleneck in X-ray crystallography.""Some crystallize easily, some crystallize hardly and some are impossible to crystallize,
"Our next grand challenge is to apply this method to protein crystallography, he says

what is determined from crystallography. As an alternative and complementary technique, structural biologists often gather diffraction patterns from particles in solution.

Because X-ray crystallography doesn reveal the structure of a material on a per-atom basis
molecules can still move X-ray crystallography reveals the three-dimensional structure of a molecule, thus making it possible to understand how it works
and that this movement"blurs"the structures obtained via crystallography. The study stresses that the more these residual movements are restricted, the better the crystalline order.
This research combines crystallography nuclear magnetic resonance (NMR) and simulation and is the result of an international cooperation involving researchers from the Institute of Structural biology (ISB, CEA/CNRS/Joseph Fourier University) in Grenoble, France, Purdue University, USA,
X-ray crystallography is the most prolific method for determining protein structures. The quality of a crystallographic structure depends on the"degree of order"within the crystal.
The researchers at IBS used a multi-technique approach, combining solid-state NMR spectroscopy, simulations of molecular dynamics and X-ray crystallography.

Using X-ray crystallography, the team obtained the first high-resolution 3d structural images of the single protein
"A common way to decipher molecular structures is to use x-ray crystallography. This complicated method involves purifying and crystallising the molecules,
"The researchers resorted to the computational approach because of the difficulty of capturing the structure via X-ray crystallography or single-particle transmission electron microscopy, two of the most common imaging methods at the atomic scale.
