STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

nnrSNnrS is a putative heme-Cu protein and a member of the short-chain dehydrogenase family, probably involved in the nitric oxide metabolism. Genes encoding putative orthologues of NnrS are sometimes but not always found in bacteria encoding nitrite and/or nitric oxide reductase. 40% NnrS. TMhelix:10 Pfam:PF05940; NnrS; 1; Function unclear. (396 aa)

nosZ
Nitrous-oxide reductase. Homology to nosZ of a. eutrophus of 78% (sprot|NOSZ_ALCEU) Nitrous-oxide reductase is part of a bacterial respiratory system which is activated under anaerobic conditions in the presence of nitrate or nitrous oxide (By similarity). no domains probable signal peptide no TMHs met_pdase_I: methionine aminopeptidas; High confidence in function and specificity.

nosL
Putative NosL protein. Homology to nosL of S. meliloti of 38% (trembl|O07331). NosL is one of the accessory proteins of the nos (nitrous oxide reductase) gene cluster. NosL is a monomeric protein of 18,540 MW that specifically and stoichiometrically binds Cu(I). The copper ion in NosL is ligated by a Cys residue, and one Met and one His are thought to serve as the other ligands. It is possible that NosL is a copper chaperone involved in metallocenter assembly. probable signal peptide no TMHs; Family membership.
