A second nitrogen fixation ( nif ) operon in the cyanobacterium (blue-green alga) Anabaena ( Nostoc ) sp. strain PCC 7120 has been identified and sequenced. It is located just upstream of the nifHDK operon and consists of four genes in the order nifB, fdxN, nifS , and nifU . The ...
Process of the Nitrogen Cycle consists of the following steps – Nitrogen fixation, Nitrification, Assimilation, Ammonification and Denitrification. These processes take place in several stages and are explained below: Nitrogen Fixation Process It is the initial step of the nitrogen cycle. Here, Atmosph...
Biological nitrogen fixation is catalyzed by the nitrogenase enzyme system which consists of two metalloproteins, the iron (Fe-) protein and the molybdenum-iron (MoFe-) protein. Together, these proteins mediate the ATP-dependent reduction of dinitrogen to ammonia. Recent crystallographic analyses of ...

It turns out that each of the two FeMo cofactors consists of an Fe4S3and an Fe3MoS3incompletecubanecluster. These are linked by two S bridges and a third bridging atom (Y), not identified with certainty, but possibly a well-ordered O or N or, alternatively, a less well-ordered S. ...

It consists of three sequential steps: (i) partial nitrification of ammonium to nitrite, (ii) partial anoxic reduction of nitrite to nitrous oxide and (iii) decomposition of nitrous oxide to N2, O2 and energy. The advantages of CANDO are the lower oxygen requirement, minimal sludge production...
