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

glmSGlutamine--fructose-6-phosphate transaminase (isomerizing); Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source. (610 aa)    
Predicted Functional Partners:
glmU
Bifunctional protein GlmU; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain.

glmM
Phosphoglucosamine mutase; Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate; Belongs to the phosphohexose mutase family.
 
 0.962
gltB
Glutamate synthase, alpha subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
   
 0.957
glnA
Glutamine synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 
 0.936
carB
Carbamoyl-phosphate synthase, large subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the CarB family.
   
 0.931
purQ
Phosphoribosylformylglycinamidine synthase, PurQ subunit (FGAM synthase I); 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 P [...]

purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
    
0.924
NIDE0356
Putative Glucose-6-phosphate isomerase (modular protein); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the GPI family.
  
 
 0.923
manC/pmi
Bifunctional Mannose-1-phosphate guanylyltransferase/Mannose-6-phosphate isomerase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the mannose-6-phosphate isomerase type 2 family.
    
 0.921
carA
Carbamoyl-phosphate synthase, small subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the CarA family.
