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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nsrRNO-dependent activator of the ResDE regulon; Nitric oxide-responsive transcriptional regulator. It represses the expression of flavohemoprotein hmp and the nitrite reductase nasD. Probably plays a role in the up-regulation of the resDE regulon in the presence of nitric oxide. (146 aa)    
Predicted Functional Partners:
hmp
Flavohemoglobin; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress (By similarity). In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.

resD
Two-component response regulator; Member of the two-component regulatory system ResD/ResE. Required for the expression of resA, ctaA, qcrABC and fnr; activation role in global regulation of aerobic and anaerobic respiration.
   
  
 0.843
resE
Two-component sensor histidine kinase; Member of the two-component regulatory system ResD/ResE involved in the global regulation of aerobic and anaerobic respiration. Probably phosphorylates ResD.

sufU
Iron-sulfur cluster assembly scaffold protein; Its function is controversial. Has been generally assumed to be an iron-sulfur cluster assembly scaffold protein , but more recent evidence suggest it is a sulfurtransferase rather than a scaffold assembly protein. Has been shown to bind low levels of a labile, air- sensitive Fe-S cluster; this can be assembled under anaerobic conditions from FeCl(3) and Li(2)S. Has been shown to be able to transfer this Fe-S cluster to an acceptor protein. Stimulates the cysteine desulfurase activity of SufS, for which it acts as a second substrate. Alkyl [...]

nasD
Assimilatory nitrite reductase subunit; Required for nitrite assimilation.
     
 0.715
ygxB
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
     
 0.669
iscSA
Cysteine desulfurase involved in tRNA thiolation; Catalyzes the removal of elemental sulfur from cysteine to produce alanine.
  
  
 0.528
nifS
Putative desulfurase involved in iron-sulfur clusters for NAD biosynthesis; Catalyzes the removal of elemental sulfur from cysteine to produce alanine (By similarity). Seems to be required for NAD biosynthesis.
  
  
 0.528
iscSB
Cysteine desulfurase; Catalyzes the removal of elemental sulfur from cysteine to produce alanine.
  
  
 0.528
ykuN
Short-chain flavodoxin; Low-potential electron donor to a number of redox enzymes. Belongs to the flavodoxin family.
