Domain

Nitrogenase/oxidoreductase, component 1 (IPR000510)

Short name: Nase/OxRdtase_comp1

Overlapping homologous superfamilies

None.

Domain relationships

None.

Description

Enzymes belonging to this family include cofactor-requiring nitrogenases and protochlorophyllide reductase. The key enzymatic reactions in nitrogen fixation are catalysed by the nitrogenase complex, which has two components, the iron protein (component 2), and a component (component 1) which is either a molybdenum-iron, vanadium-iron or iron-iron protein. The enzyme (EC:1.18.6.1) forms a hexamer of two alpha, two beta and two delta chains. Protochlorophyllide reductase (EC:1.3.1.33) is involved in the light-dependent accumulation of chlorophyll, probably at the step of reduction of protochlorophyllide to chlorophyllide.
