“Protein Crystallography is a form of very high-resolution microscopy, which enables scientists to “see” at atomic resolution. It allows us to see beyond the capabilities of even the most powerful light microscope.Mar 11, 2020.
We use protein crystallography to determine, experimentally, the structure of proteins. The method applies to other macromolecules, such as nucleic acid and viruses. All structural data for every protein solved sits in online repositories and is free for scientists to access and interrogate.Jan 31, 2023
That's what happens in protein crystallography. We measure the diffracted X-rays, quantify them, feed them back into the Fourier transform, and raise it to the power of minus one (reciprocate it). This process results in a three-dimensional map of all the electron densities (where electrons are) in the asymmetric unit.

Protein crystallography is used for determining the molecular structure of proteins. Crystallized protein molecules cause a beam of incident x-rays to scatter in many directions, with constructive and destructive interference generating a diffraction pattern. By analyzing these patterns, a crystallographer can produce a ...“Protein Crystallography is a form of very high-resolution microscopy, which enables scientists to “see” at atomic resolution.

Crystallographic study of protein
Maltose-binding protein (MBP) is a part of the maltose/maltodextrin system of Escherichia coli, which is responsible for the uptake and efficient catabolism of maltodextrins. It is a complex regulatory and transport system involving many proteins and protein complexes. MBP has an approximate molecular mass of 42.5 kilodaltons.
Protein A is a 42 kDa surface protein originally found
Protein A is a 42 kDa surface protein originally found in the cell wall of the bacteria Staphylococcus aureus. It is encoded by the spa gene and its regulation is controlled by DNA topology, cellular osmolarity, and a two-component system called ArlS-ArlR. It has found use in biochemical research because of its ability to bind immunoglobulins. It is composed of five homologous Ig-binding domains that fold into a three-helix bundle. Each domain is able to bind proteins from many mammalian species, most notably IgGs. It binds the heavy chain within the Fc region of most immunoglobulins and also within the Fab region in the case of the human VH3 family. Through these interactions in serum, where IgG molecules are bound in the wrong orientation, the bacteria disrupts opsonization and phagocytosis.
Retinol binding protein 4
Protein-coding gene in the species Homo sapiens
Retinol binding protein 4, also known as RBP4, is a transporter protein for retinol. RBP4 has a molecular weight of approximately 21 kDa and is encoded by the RBP4 gene in humans. It is mainly, though not exclusively, synthesized in the liver and circulates in the bloodstream as a hepatokine bound to retinol in a complex with transthyretin. RBP4 has been a drug target for ophthalmology research due to its role in vision. RBP4 may also be involved in metabolic diseases as suggested by recent studies.
Soy protein is a protein that is isolated from soybean
A protein that is isolated from soybean
Soy protein is a protein that is isolated from soybean. It is made from soybean meal that has been dehulled and defatted. Dehulled and defatted soybeans are processed into three kinds of high protein commercial products: soy flour, concentrates, and isolates. Soy protein isolate has been used since 1959 in foods for its functional properties.
