Protein Family Models

This family is the gamma subunit of the nitrate reductase enzyme, the gamma subunit is a b-type cytochrome that receives electrons from the quinone pool [1]. It then transfers these via the iron-sulfur clusters of the beta subunit to the molybdenum cofactor found in the alpha subunit [1]. The nitrate reductase enzyme, EC:1.7.99.4 catalyses the conversion of nitrite to nitrate via the reduction of an acceptor. The nitrate reductase enzyme is composed of three subunits [1]. Nitrate is the most widely used alternative electron acceptor after oxygen [1]. [1]. 9738886. Identification and characterization of the Staphylococcus. carnosus nitrate reductase operon..

Involved in anerobic respiration the gene product catalyzes the reaction (reduced acceptor + NO3- = Acceptor + nitrite). Another possible role_id for this gene product is in nitrogen fixation (Role_id:160).
