X-ray crystallography is one of the essential components in bubblegram imaging as it is the process of how X-ray radiation is used to identify structures and surfaces of specimens. The electromagnetic radiation emitted is from the charged electrons being controlled to reveal the patterns formed by the protein.
X-ray crystallography is still the primary method for characterizing the atomic structure of materials and in differentiating materials that appear similar in other experiments. X-ray crystal structures can also help explain unusual electronic or elastic properties of a material, shed light on chemical interactions and processes, or serve as ...
Cell structure of a gram positive bacterium. In comparison to eukaryotes, the intracellular features of the bacterial cell are extremely simple. Bacteria do not contain organelles in the same sense as eukaryotes. Instead, the chromosome and perhaps ribosomes are the only easily observable intracellular structures found in all bacteria. There do ...
The most prominent techniques are X-ray crystallography, nuclear magnetic resonance, and electron microscopy. Through the discovery of X-rays and its applications to protein crystals, structural biology was revolutionized, as now scientists could obtain the three-dimensional structures of biological molecules in atomic detail.

Prior to Bernal and Hodgkin, protein crystallography had only been performed in dry conditions with inconsistent and unreliable results. This is the first X‐ray diffraction pattern of a protein crystal. [8] In 1958, the structure of myoglobin (a red protein containing heme), determined by X-ray crystallography, was first reported by John ...
The structure of the complex has been variously elucidated through X-ray crystallography and EM data, and suggest that the complex consists of either one or two RuvA tetramers, with charge lined grooves through which the incoming DNA is channelled. The structure also showed the presence of so-called 'acidic pins' in the centre of the tetramer ...
The SP family includes the well characterized maltoporin of E. coli for which the three-dimensional structures with and without its substrate have been obtained by X-ray diffraction. The protein consists of an 18 β-stranded β-barrel in contrast to proteins of the general bacterial porin family (GBP) and the Rhodobacter PorCa Porin (RPP ...
Proteins known to form the shell have been structurally characterized by X-ray crystallography. The proteins that constitute the majority of the shell form cyclical hexamers or pseudo-hexamers and belong to the BMC protein family . [ 21 ]
