Crystallographic studies of some tetracyaquidimethane complexes.
The solid state structures of charge-transfer complexes of 7,7,8,8-tetracyanoquinodimethane, TCNQ, have been reviewed and classified into three main structural types viz homosoric (pseudosoric), heterosoric, and nonsoric. In an attempt to more fully understand the factors influencing the type of …

Crystallographic studies on enzymatic halogenation of natural products
Halogenated natural products are common and serve roles as hormones, pesticides, antibiotics, and anti-tumor agents. The incorporation of a halogen atom into an organic scaffold can tune the molecule's potency and selectivity, making halogenation an important tailoring reaction. To understand the …

Crystallographic studies on diheme cytochrome <i>c</i> enzymes
Abhängig von ihrer Umwelt und ihrem physiologischen Zustand bilden Bakterien unterschiedliche Elektronentransportketten aus. Elektronentransportsysteme in der inneren Membran übertragen Elektronen von verschiedenen Elektronendonoren wie NADH, organischen Molekülen oder Wasserstoff an lösliche …

Crystallographic studies of interactions between ligands and DNA oligonucleotides
… in Chapter One are two out of only five crystallographic quadruplex/ligand structures reported to date. In both structures daunomycin molecules stack onto a terminal G quartet preventing the G4 quadruplex from destacking and unwinding. The number of interacting ligand molecules depends on …

Crystallographic studies of the metal-responsive transcription factor NikR
Metal ion homeostasis is critical to the survival of all cells, because requirements for these essential nutrients must be balanced with their toxicity when present at elevated concentrations. Regulation of nickel concentrations in Escherichia coli is achieved via nickel-induced transcriptional …

SYNTHESIS, TESTING AND CRYSTALLOGRAPHIC STUDIES OF ALLOSTERIC MODIFIERS OF HEMOGLOBIN
… for their anti-sickling activities. Structural studies were carried out to gain insight into the compound’s mode of action. Development of these agents could be a therapeutic strategy for SCD or ischemic-related diseases.

Crystallographic studies on a cold adapted subtilase and proteins involved in mRNA processing
Die Kristallstruktur einer Subtilisin-ähnlichen Serin-Proteinase des psychrotrophen marinen Bakteriums, Vibrio sp. PA-44, wurde durch molekularen Ersatz bei 1,84 Å Auflösung aufgeklärt. Damit konnte zum ersten Mal die Struktur einer kälteadaptiven Subtilase aufgeklärt werden. Dies macht es möglich, …

Crystallographic Studies of Cation-Glucuronic Acid Interactions: Structures of Calcium-Bromide Glucuronate and Sodium Glucuronate.
Calcium complexes of polysaccharides that contain D-glucuronate residues have been implicated in such biological processes as calcium storage, calcification, and calcium-dependent cell-cell adhesion. In 1957, Farber, Schubert and Schuster investigated the binding of sodium, potassium, and calcium …
