Bacterial nitrate reductases: Molecular and biological aspects of nitrate reduction.
Nitrogen is a vital component in living organisms as it participates in the making of essential biomolecules such as proteins, nucleic acids, etc. In the biosphere, nitrogen cycles between theExpand
BiGGER: A new (soft) docking algorithm for predicting protein interactions
A new computationally efficient and automated “soft docking” algorithm is described to assist the prediction of the mode of binding between two proteins, using the three‐dimensional structures of theExpand
Metalloenzymes of the denitrification pathway.
Denitrification, or dissimilative nitrate reduction, is an anaerobic process used by some bacteria for energy generation. This process is important in many aspects, but its environmental implicationsExpand
Nitrite reductase activity of rat and human xanthine oxidase, xanthine dehydrogenase, and aldehyde oxidase: evaluation of their contribution to NO formation in vivo.
Nitrite is presently considered a NO "storage form" that can be made available, through its one-electron reduction, to maintain NO formation under hypoxia/anoxia. The molybdoenzymes xanthineExpand

Nitric oxide (NO) is a signalling molecule involved in several physiological processes, in both prokaryotes and eukaryotes, and nitrite is being recognised as an NO source particularly relevant toExpand
Crystal Structure of the Xanthine Oxidase-Related Aldehyde Oxido-Reductase from D. gigas
The crystal structure of the aldehyde oxido-reductase (Mop) from the sulfate reducing anaerobic Gram-negative bacterium Desulfovibrio gigas has been determined at 2.25 Å resolution by multipleExpand
Crystal structure of the first dissimilatory nitrate reductase at 1.9 A solved by MAD methods.
BACKGROUND The periplasmic nitrate reductase (NAP) from the sulphate reducing bacterium Desulfovibrio desulfuricans ATCC 27774 is induced by growth on nitrate and catalyses the reduction of nitrateExpand
Mo and W bis-MGD enzymes: nitrate reductases and formate dehydrogenases
Molybdenum and tungsten are second- and third-row transition elements, respectively, which are found in a mononuclear form in the active site of a diverse group of enzymes that generally catalyzeExpand

The reduction of nitrate to nitrogen gas via nitrite, nitric oxide and nitrous oxide is the metabolic pathway usually known as denitrification, a key step in the nitrogen cycle. As observed for otherExpand
ATP sulfurylases from sulfate-reducing bacteria of the genus Desulfovibrio. A novel metalloprotein containing cobalt and zinc.
Adenosine triphosphate sulfurylase catalyzes the formation of adenosine 5'-phosphosulfate from adenosine triphosphate and sulfate. The enzyme plays a crucial role in sulfate activation, the key stepExpand
