>TIGR01660 narH nitrate reductase, beta subunit; InterPro: IPR006547 The nitrate reductase enzyme complex allows bacteria to use nitrate as an electron acceptor during anaerobic growth. The enzyme complex consists of a tetramer that has an alpha, beta and 2 gamma subunits. The alpha and beta subunits have catalytic activity and the gamma subunits attach the enzyme to the membrane and are b-type cytochromes that receive electrons from the quinone pool and transfers them to the beta subunit. The sequences in this family are the beta subunit for nitrate reductase I (narH) and nitrate reductase II (narY) for Gram-positive and Gram-negative bacteria. A few thermophiles and archaea also match the model. A number of the sequences in this set are experimentally characterised, these include: E.Coli NarH (P11349 from SWISSPROT) and NarY (P19318 from SWISSPROT) , , P42176 from SWISSPROT from Bacillus subtilis, and related proteins from Psuedomonas fluorescens, Paracoccus denitrificans, and Halomonas halodenitrificans.; GO: 0008940 nitrate reductase activity, 0042126 nitrate metabolic process, 0009325 nitrate reductase complex.
