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

nagBBGlucosamine-6-phosphate isomerase; 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. (249 aa)    
Predicted Functional Partners:
gamP
Phosphotransferase system (PTS) glucosamine-specific enzyme IICBA 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 may be involved in glucosamine transport.
 
 
 0.999
nagA
N-acetylglucosamine-6-phosphate deacetylase; Involved in the first committed 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; Belongs to the metallo-dependent hydrolases superfamily. NagA family.
 0.999
glmS
L-glutamine-D-fructose-6-phosphate amidotransferase; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source.
  
 
 0.986
pgi
Glucose-6-phosphate isomerase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the GPI family.
  
 0.955
ybcM
Putative enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
 
 0.947
glmM
Phosphoglucosamine mutase; Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate (By similarity). Glucosamine-1-phosphate is used for cell wall biosynthesis (Probable); Belongs to the phosphohexose mutase family.
 
 
 0.946
ybgA
Putative transcriptional regulator (GntR family); Transcriptional repressor of genes involved in glucosamine transport and utilization. Represses the expression of the gamAP operon by binding to the gamA-gamR intergenic region.
  
  
 0.930
nagP
Phosphotransferase system (PTS) N-acetylglucosamine-specific enzyme IICB 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 (By similarity).
  
 0.917
gmuE
ROK fructokinase; Seems to be involved in the degradation of glucomannan.
    
 0.913
ydjE
Putative sugar kinase (ribokinase family); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the carbohydrate kinase PfkB family.
