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

glnAGlutamine synthetase (glnA); Probably involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Beta-glutamate is a much poorer substrate than alpha-glutamate; Belongs to the glutamine synthetase family. (491 aa)    
Predicted Functional Partners:
carB
Carbamoyl-phosphate synthase, large (or ammonia) subunit (carB); Similar to PID:1001613 PID:1001668 percent identity: 65.08; identified by sequence similarity; putative.
 
 
 0.966
carA
Carbamoyl-phosphate synthase, small (or glutamine) subunit (carA); Similar to GB:L77117 SP:Q58425 PID:1591677 percent identity: 55.17; identified by sequence similarity; putative; Belongs to the CarA family.

gltB
Glutamate synthase (gltB); Similar to PID:1591994 GB:L77117 PID:1591994 percent identity: 57.85; identified by sequence similarity; putative; Belongs to the glutamate synthase family.

purF
Amidophosphoribosyltransferase (purF); Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
  
 0.945
AF_0164
Ferredoxin-nitrite reductase (nirA); Similar to PID:1001216 PID:1001208 percent identity: 29.72; identified by sequence similarity; putative.
    
 0.944
AF_0673
Mercuric resistance operon regulatory protein (merR); Similar to SP:P22853 PID:1129093 percent identity: 33.04; identified by sequence similarity; putative.
 
 
 0.928
purQ
Phosphoribosylformylglycinamidine synthase I (purQ); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to a [...]
    
 0.920
gltX
glutamyl-tRNA synthetase (gltX); Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu).
   
 0.862
trpCD
Anthranilate synthase component II (trpD); Bifunctional enzyme that catalyzes the second and fourth steps of tryptophan biosynthetic pathway. The second step is catalyzed by the anthranilate phosphoribosyltransferase, coded by the TrpD domain and the fourth step is catalyzed by indole-3-glycerol phosphate synthase, coded by the TrpC domain (By similarity).
