Cluster assembly in nitrogenase
Essays in Biochemistry, 2017The versatile enzyme system nitrogenase accomplishes the challenging reduction of N2and other substrates through the use of two main metalloclusters. For molybdenum nitrogenase, the catalytic component NifDK contains the [Fe8S7]-core P-cluster and a [MoFe7S9C-homocitrate] cofactor called the M-cluster.

Crystallization of Nitrogenase Proteins
2018Nitrogenase is the only known enzymatic system capable of reducing atmospheric dinitrogen to ammonia. This unique reaction requires tightly choreographed interactions between the nitrogenase component proteins, the molybdenum-iron (MoFe)- and iron (Fe)-proteins, as well as regulation of electron transfer between multiple metal centers that are only ...

An alternative nitrogenase enzyme that only utilizes iron as its cofactor is shown to reduce carbon dioxide while actively fixing dinitrogen, so that it simultaneously produces ammonium, hydrogen and methane.

Purification of Nitrogenase Proteins
2011Nitrogenase is one of the most complex enzymes known to date. The extensively studied molybdenum nitrogenase consists of two protein components and three metal centers that are critical for nitrogenase activity. The inherent complexity of this enzyme system, which is further compounded by the sensitivity of the metal clusters toward oxygen, makes the ...

Advances in inorganic biochemistry, 1990
Recently, it has been demonstrated that both A. vinelandii and A. chroococcum have the ability to synthesize several different nitrogen-fixing enzymes. Both species can produce a Mo- or V-containing nitrogenase while A. vinelandii can also generate an all-Fe form of the enzyme.

Abstract Nitrogenases are a family of metalloenzymes that catalyse a key step in the global nitrogen cycle: the adenosine triphosphate (ATP)-dependent reduction of dinitrogen (N2) to ammonia (NH3). The molybdenum (Mo)-nitrogenase is the best characterised member of this enzyme family.
