9-154 5.31e-37

nitrate reductase molybdenum cofactor assembly chaperone; This protein is termed NarJ in most species that have a single copy, and has been called the delta subunit of nitrate reductase. However, although it is required for correct assembly of active enzyme, it dissociates and is not part of the enzyme. Two hits to this model are found each in E. coli and in Mycobacterium tuberculosis, but in each case duplication to create paralogs appears to be recent. The NarX protein of Mycobacterium tuberculosis includes one of these paralogs as a domain, fused to structural domains of nitrate reductases before and after the NarJ-homologous region.

45-153 3.11e-09

Nitrate reductase delta subunit; This family is the delta subunit of the nitrate reductase enzyme, The delta subunit is not part of the nitrate reductase enzyme but is most likely needed for assembly of the multi-subunit enzyme complex. In the absence of the delta subunit the core alpha beta enzyme complex is unstable. The delta subunit is essential for enzyme activity in vivo and in vitro. The nitrate reductase enzyme, EC:1.7.99.4 catalyze the conversion of nitrite to nitrate via the reduction of an acceptor. The nitrate reductase enzyme is composed of three subunits. Nitrate is the most widely used alternative electron acceptor after oxygen. This family also now contains the family TorD, a family of cytoplasmic chaperone proteins; like many prokaryotic molybdoenzymes, the TMAO reductase (TorA) of Escherichia coli requires the insertion of a bis(molybdopterin guanine dinucleotide) molybdenum (bis(MGD)Mo) cofactor in its catalytic site to be active and translocated to the periplasm. The TorD chaperone increases apoTorA activation up to four-fold, allowing maturation of most of the apoprotein. Therefore TorD is involved in the first step of TorA maturation to make it competent to receive the cofactor.
