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

cpsBMannose-1-phosphate guanyltransferase; Involved in the biosynthesis of the capsular polysaccharide colanic acid. (478 aa)    
Predicted Functional Partners:
cpsG
Phosphomannomutase; Involved in the biosynthesis of the capsular polysaccharide colanic acid; Belongs to the phosphohexose mutase family.
 
 0.999
gmd
GDP-D-mannose dehydratase, NAD(P)-binding; Catalyzes the conversion of GDP-D-mannose to GDP-4-dehydro-6- deoxy-D-mannose; Belongs to the NAD(P)-dependent epimerase/dehydratase family. GDP-mannose 4,6-dehydratase subfamily.
 
 
 0.998
wcaJ
Colanic biosynthesis UDP-glucose lipid carrier transferase; Is the initiating enzyme for colanic acid (CA) synthesis. Catalyzes the transfer of the glucose-1-phosphate moiety from UDP-Glc onto the carrier lipid undecaprenyl phosphate (C55-P), forming a phosphoanhydride bond yielding to glucosyl-pyrophosphoryl-undecaprenol (Glc-PP-C55). Also possesses a weak galactose-1-P transferase activity. Belongs to the bacterial sugar transferase family.
 
  
 0.992
wcaG
GDP-L-fucose synthase; Catalyzes the two-step NADP-dependent conversion of GDP-4- dehydro-6-deoxy-D-mannose to GDP-fucose, involving an epimerase and a reductase reaction. Belongs to the NAD(P)-dependent epimerase/dehydratase family. Fucose synthase subfamily.
 
  
 0.973
wcaI
Putative colanic biosynthesis glycosyl transferase; Protein involved in colanic acid biosynthetic process.
 
  
 0.948
wcaH
GDP-mannose mannosyl hydrolase; Hydrolyzes both GDP-mannose and GDP-glucose. Could participate in the regulation of cell wall biosynthesis by influencing the concentration of GDP-mannose or GDP-glucose in the cell. Might also be involved in the biosynthesis of the slime polysaccharide colanic acid; Belongs to the Nudix hydrolase family.
 
  
 0.941
wcaA
Putative glycosyl transferase; Putative regulator; Protein involved in colanic acid biosynthetic process.
 
  
 0.920
wzc
Colanic acid production tyrosine-protein kinase; Required for the extracellular polysaccharide colanic acid synthesis. The autophosphorylated form is inactive. Probably involved in the export of colanic acid from the cell to medium. Phosphorylates udg.
 
  
 0.919
rfbC
dTDP-4-deoxyrhamnose-3,5-epimerase; Catalyzes the epimerization of the C3' and C5'positions of dTDP-6-deoxy-D-xylo-4-hexulose, forming dTDP-6-deoxy-L-lyxo-4-hexulose. Belongs to the dTDP-4-dehydrorhamnose 3,5-epimerase family.
 
  
 0.905
wzb
Colanic acid production protein-tyrosine-phosphatase; Dephosphorylates Wzc. Required for the extracellular polysaccharide colanic acid synthesis, probably involved in the export of colanic acid from the cell to medium. Involved in protection of cells against contact- dependent growth inhibition (CDI), probably due to the loss of a physical impediment to cell-cell contact; Belongs to the low molecular weight phosphotyrosine protein phosphatase family.
