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.

ntrBNitrogen regulation protein NtrB. (384 aa)    
Predicted Functional Partners:
ntrC
Response regulator for gln; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
 0.998
ACP25247.1
Nitrogen regulatory protein P-II; Belongs to the P(II) protein family.
  
 0.977
nifR
tRNA-dihydrouridine synthase; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines; Belongs to the dus family.
  
  
 0.892
ntrX
Nitrogen assimilation regulatory protein, NtrX.
 
 
 0.874
ACP26447.1
Putative two-component response regulator transcriptional regulatory protein.
 
 
 0.787
ACP26884.1
Ammonium transport protein; Amt family.
  
 
 0.784
ACP26885.1
Putative nitrogen regulatory protein PII; Belongs to the P(II) protein family.
  
 
 0.782
ACP26587.1
Sigma-54 dependent DNA-binding response regulator.
 
 
 0.780
glnD
[Protein-PII] uridylyltransferase; Modifies, by uridylylation and deuridylylation, the PII regulatory proteins (GlnB and homologs), in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen fixation and metabolism.
