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

glmSL-glutamine:D-fructose-6-phosphate aminotransferase; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source. (609 aa)    
Predicted Functional Partners:
glmU
Fused N-acetyl glucosamine-1-phosphate uridyltransferase/glucosamine-1-phosphate acetyl transferase; 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. Can also catalyze the formation of glucose-6-P from glucose-1-P, although at a 1400-fold lower rate.
 
 0.996
nagB
Glucosamine-6-phosphate deaminase; Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion; Belongs to the glucosamine/galactosamine-6-phosphate isomerase family. NagB subfamily.
  
 
 0.976
pgi
Glucosephosphate isomerase; Protein involved in glycolysis and gluconeogenesis; Belongs to the GPI family.
  
 
 0.966
nagA
N-acetylglucosamine-6-phosphate deacetylase; Involved in the first step in the biosynthesis of amino- sugar-nucleotides. Catalyzes the hydrolysis of the N-acetyl group of N- acetylglucosamine-6-phosphate (GlcNAc-6-P) to yield glucosamine 6- phosphate and acetate. In vitro, can also hydrolyze substrate analogs such as N-thioacetyl-D-glucosamine-6-phosphate, N-trifluoroacetyl-D- glucosamine-6-phosphate, N-acetyl-D-glucosamine-6-sulfate, N-acetyl-D- galactosamine-6-phosphate, and N-formyl-D-glucosamine-6-phosphate.

gltB
Glutamate synthase, large subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate.
  
 0.948
yhbJ
Adaptor protein for GlmZ/GlmY sRNA decay, glucosamine-6-phosphate-regulated; Modulates the synthesis of GlmS, by affecting the processing and stability of the regulatory small RNA GlmZ. When glucosamine-6- phosphate (GlcN6P) concentrations are high in the cell, RapZ binds GlmZ and targets it to cleavage by RNase E. Consequently, GlmZ is inactivated and unable to activate GlmS synthesis. Under low GlcN6P concentrations, RapZ is sequestered and inactivated by an other regulatory small RNA, GlmY, preventing GlmZ degradation and leading to synthesis of GlmS. Displays ATPase and GTPase acti [...]

glnA
Glutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia.
  
 
 0.943
carB
Carbamoyl-phosphate synthase large subunit; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process; Belongs to the CarB family.
  
 0.942
carA
Carbamoyl phosphate synthetase small subunit, glutamine amidotransferase; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process.
