unusual facts about crystal structure



Allosteric enzyme

Hemoglobin, though not an enzyme, is the canonical example of an allosteric protein molecule - and one of the earliest to have its crystal structure solved (by Max Perutz).

Arginine:glycine amidinotransferase

The crystal structure of AGAT was determined by Humm, Fritsche, Steinbacher, and Huber of the Max Planck Institute of Biochemistry in Martinsried, Germany in 1997.

Blue phase mode LCD

The defects that occur at regular distances in three spatial dimensions form a cubic lattice just as we know it from solid crystals.

Moritz Ludwig Frankenheim

By 1826, he was already using the integer reciprocals of Weiss' coefficients (the intersection of a plane with the three crystallographic axes) to describe the spatial positions of crystal surfaces, from which the British crystallographer William Hallowes Miller (1801-1880) developed the concept of Miller indices in 1839.

Yigong Shi

In 1995 when receiving his PhD degree in Biophysics from Johns Hopkins University, he has determined the crystal structure of several critical apoptotic proteins, including apaf-1, DIAP1, and the BIR3 domain of XIAP.

Jon Clardy

Clardy, in collaboration with Stuart Schreiber and colleagues, obtained the crystal structure for both the FK506/FKBP12 and rapamycin/FKBP12 complexes.

KcsA potassium channel

An aspect of KcsA that has not been fully addressed by simulation studies is that the crystal structure appears to be that of the ‘closed' form of the channel.

Krzysztof Palczewski

His work with determining the crystal structure of rhodopsin has given new insight into the function of G protein receptors.

Martensite

Martensite, named after the German metallurgist Adolf Martens (1850–1914), most commonly refers to a very hard form of steel crystalline structure, but it can also refer to any crystal structure that is formed by diffusionless transformation.

Pyroelectricity

All crystal structures can be divided into 32 crystal classes, according to the number of rotational axes and reflection planes they exhibit that leave the crystal structure unchanged.
