Nitrite Inhibition of Bacterial Dinitrogen Fixation

Bacterial Nitrogenase, Nitrite Inhibition, Dinitrogenase Reductase Dinitrogen fixation by crude extracts from Rhodopseudomonas palustris and Rhodomicrobium vannielii and by purified nitrogenase preparations from Azotobacter vinelandii and Clostridium pasteurianum is inhibited by nitrite, whereas in the same preparations nitrate is without effect. In Clostridium nitrite seems to interact with di...

Studies on Bacterial Enzymes

The meningococcus cell contains a peptonase enzyme which hydrolyzes the peptides and similar constituents of commercial "peptone." The activity of this enzyme is independent of the presence of the formed bacterial cell. The peptonase enzyme is more resistant to heat and to oxidation than is the maltase enzyme of the same bacteria.

Bacterial enzymes Hyaluronidase

Bacterial enzyme ‘Hyaluronidase’ is a complex polysaccharide degrading enzyme that cleaves â-GlcNAc-(14) glycosidic linkage of Hyaluronate (HA) by â-elimination process. It is synthesized by a spectrum of grampositive bacteria which serve as potential contributors to a multitude of infectious diseases in human beings. Especially, group A streptococcus bacteria (GAS) have evolved several orders...

Nitrite Biosensing via Selective Enzymes—A Long but Promising Route

The last decades have witnessed a steady increase of the social and political awareness for the need of monitoring and controlling environmental and industrial processes. In the case of nitrite ion, due to its potential toxicity for human health, the European Union has recently implemented a number of rules to restrict its level in drinking waters and food products. Although several analytical ...

Molecular characterization of the nitrite-reducing system of Staphylococcus carnosus.

Characterization of a nitrite reductase-negative Staphylococcus carnosus Tn917 mutant led to the identification of the nir operon, which encodes NirBD, the dissimilatory NADH-dependent nitrite reductase; SirA, the putative oxidase and chelatase, and SirB, the uroporphyrinogen III methylase, both of which are necessary for biosynthesis of the siroheme prosthetic group; and NirR, which revealed n...
