NosD is a periplasmic protein which is thought to insert copper into the exported reductase apoenzyme (NosZ) [1]. This region forms a parallel beta helix domain. [1]. 8626275.

nitrous oxide reductase family maturation protein NosD is required for the assembly of the copper chromophores of nitrous oxide reductase

Members of this family include NosD, a repetitive periplasmic protein required for the maturation of the copper-containing enzyme nitrous-oxide reductase. NosD appears to be part of a complex with NosF (an ABC transporter family ATP-binding protein) and NosY (a six-helix transmembrane protein in the ABC-2 permease family). However, NosDFY-like complexes appear to occur also in species whose copper requiring enzymes are something other than nitrous-oxide reductase.

This model represents a tandem pair of an approximately 22-amino acid (each) repeat homologous to the beta-strand repeats that stack in a right-handed parallel beta-helix in the periplasmic C-5 mannuronan epimerase, AlgA, of Pseudomonas aeruginosa. A homology domain consisting of a longer tandem array of these repeats is described in the SMART database as CASH (SM00722), and is found in many carbohydrate-binding proteins and sugar hydrolases. A single repeat is represented by SM00710. This TIGRFAMs model represents a flavor of the parallel beta-helix-forming repeat based on prokaryotic sequences only in its seed alignment, although it also finds many eukaryotic sequences.
