Nitrogenases are responsible for biological nitrogen fixation, a crucial step in the
biogeochemical nitrogen cycle. These enzymes utilize a two-component protein system and …

Recent developments in microwave technologies have led to a renaissance of electron
paramagnetic resonance (EPR) due to the implementation of new spectrometers operating …

Ribonucleotide reductases (RNRs) catalyze the reduction of ribonucleotides to
deoxyribonucleotides, thereby playing a key role in DNA replication and repair. Escherichia …

Hsp90 plays a central role in cell homeostasis by assisting folding and maturation of a large
variety of clients. It is a homo-dimer, which functions via hydrolysis of ATP-coupled to …

Spectroscopic and biophysical methods for structural determination at atomic resolution are
fundamental in studies of biological function. Here we introduce an approach to measure …

N2 binds to the active-site metal cluster in the nitrogenase MoFe protein, the FeMo-cofactor
([7Fe-9S-Mo-homocitrate-X]; FeMo-co) only after the MoFe protein has accumulated three or …

Ribonucleotide reductases (RNRs) catalyze the conversion of ribonucleotides to
deoxyribonucleotides in all organisms. In all Class Ia RNRs, initiation of nucleotide …

A new and easy method for preparing blue sodalite pigments which involves high-
temperature calcination of sodalite samples synthesized with aluminum sulfate and an …

Modern pulse EPR experiments are routinely used to study the structural features of
paramagnetic centers. They are usually performed at low temperatures, where relaxation …

A versatile control software for pulse EPR spectrometers is introduced. Common and task‐
specific problems are discussed and their solutions are described. The software provides …
