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

nasDAssimilatory nitrite reductase subunit; Required for nitrite assimilation. (805 aa)    
Predicted Functional Partners:
nasE
Assimilatory nitrite reductase subunit; Required for nitrite assimilation. Required for activity of the reductase (By similarity).
 
 0.999
nasC
Assimilatory nitrate reductase (catalytic subunit); Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria.
 
 0.999
narG
Nitrate reductase (alpha subunit); The alpha chain is the actual site of nitrate reduction.
  
 
 0.998
narH
Nitrate reductase (beta subunit); The beta chain is an electron transfer unit containing four cysteine clusters involved in the formation of iron-sulfur centers. Electrons are transferred from the gamma chain to the molybdenum cofactor of the alpha subunit.
  
 
 0.994
narK
Nitrite extrusion permease; Involved in excretion of nitrite produced by the dissimilatory reduction of nitrate; Belongs to the major facilitator superfamily. Nitrate/nitrite porter (TC 2.A.1.8) family.
 
 
 0.994
nasA
Putative nitrate transporter; May function as a nitrate transporter.
 
 
 0.990
narI
Nitrate reductase (gamma subunit); The gamma chain is a membrane-embedded heme-iron unit resembling cytochrome b, which transfers electrons from quinones to the beta subunit.
  
 
 0.990
nasF
uroporphyrin-III C-methyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the precorrin methyltransferase family.
 
  
 0.975
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.
  
  
 0.975
glnA
Glutamine synthetase; Glutamine synthetase (GS) is an unusual multitasking protein that functions as an enzyme, a transcription coregulator, and a chaperone in ammonium assimilation and in the regulation of genes involved in nitrogen metabolism. It catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Feedback-inhibited GlnA interacts with and regulates the activity of the transcriptional regulator TnrA. During nitrogen limitation, TnrA is in its DNA- binding active state and turns on the transcription of genes required for nitrogen assimilation. Under condi [...]
