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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nagBGlucosamine-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 (266 aa)    
Predicted Functional Partners:
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
 0.999
nagE
PTS system N-acetylglucosamine-specific EIICBA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N- acetylglucosamine transport. It can also transport and phosphorylate the antibiotic streptozotocin. Could play a significant role in the recycling of peptidoglycan
   
 0.983
nagC
N-acetylglucosamine repressor; Acts as a repressor of the nagEBACD operon and acts both as an activator and a repressor for the transcription of the glmSU operon
 
 
 0.971
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
  
 
 0.927
pgi
Glucose-6-phosphate isomerase; Protein involved in glycolysis and gluconeogenesis; Belongs to the GPI family
  
 
 0.918
mak
Fructokinase; Catalyzes the phosphorylation of fructose to fructose-6- P. Has also low level glucokinase activity in vitro. Is not able to phosphorylate D-ribose, D-mannitol, D-sorbitol, inositol, and L-threonine
    
 0.916
manA
Mannose-6-phosphate isomerase; Involved in the conversion of glucose to GDP-L-fucose, which can be converted to L-fucose, a capsular polysaccharide
     
 0.911
nanE
Putative N-acetylmannosamine-6-phosphate 2-epimerase; Converts N-acetylmannosamine-6-phosphate (ManNAc-6-P) to N-acetylglucosamine-6-phosphate (GlcNAc-6-P)
 
   
 0.893
glmS
Glutamine--fructose-6-phosphate aminotransferase [isomerizing]; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source
  
 
 0.883
nanK
N-acetylmannosamine kinase; Catalyzes the phosphorylation of N-acetylmannosamine (ManNAc) to ManNAc-6-P. Has also low level glucokinase activity in vitro; Belongs to the ROK (NagC/XylR) family. NanK subfamily
