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.

AmtBAmmonium transporter; COG0004 Ammonia permease. (452 aa)    
Predicted Functional Partners:
GlnB
COG0347 Nitrogen regulatory protein PII; Belongs to the P(II) protein family.
 
 
 0.998
glnD
PII uridylyl-transferase; 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 assimilation and metabolism.
 
   
 0.970
GltB-2
Glutamate synthase (NADPH/NADH) large chain; COG0067 Glutamate synthase domain 1.
 
  
 0.934
GltB
Glutamate synthase (NADPH/NADH) large chain; COG0067 Glutamate synthase domain 1.
 
  
 0.932
GlnA
COG0174 Glutamine synthetase.
 
  
 0.893
GlnA2
COG0174 Glutamine synthetase.
  
  
 0.715
GlnA4-1
Glutamine synthetase-like protein; COG0174 Glutamine synthetase.
  
  
 0.649
cysC
Bifunctional sulfate adenylyltransferase subunit 1/adenylylsulfate kinase protein; Catalyzes the synthesis of activated sulfate. Belongs to the APS kinase family.
      
 0.618
nadE
NAD+ synthase (glutamine-hydrolysing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
     
 0.612
trpA
Tryptophan synthase subunit alpha; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
