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

wzzEEntobacterial Common Antigen (ECA) polysaccharide chain length modulation protein; Modulates the polysaccharide chain length of enterobacterial common antigen (ECA). Required for the assembly of the phosphoglyceride-linked form of ECA (ECA(PG)) and the water-soluble cyclic form of ECA (ECA(CYC)). (348 aa)    
Predicted Functional Partners:
wecA
UDP-GlcNAc:undecaprenylphosphate GlcNAc-1-phosphate transferase; Catalyzes the transfer of the GlcNAc-1-phosphate moiety from UDP-GlcNAc onto the carrier lipid undecaprenyl phosphate (C55-P), yielding GlcNAc-pyrophosphoryl-undecaprenyl (GlcNAc-PP-C55). It is the first lipid-linked intermediate involved in enterobacterial common antigen (ECA) synthesis, and an acceptor for the addition of subsequent sugars to complete the biosynthesis of O-antigen lipopolysaccharide (LPS) in many E.coli O types. The apparent affinity of WecA for the polyisoprenyl phosphate substrates increases with the [...]

wecC
UDP-N-acetyl-D-mannosaminuronic acid dehydrogenase; Catalyzes the four-electron oxidation of UDP-N-acetyl-D- mannosamine (UDP-ManNAc), reducing NAD(+) and releasing UDP-N- acetylmannosaminuronic acid (UDP-ManNAcA).
  
  
 0.968
wecB
UDP-N-acetyl glucosamine-2-epimerase; Catalyzes the reversible epimerization at C-2 of UDP-N- acetylglucosamine (UDP-GlcNAc) and thereby provides bacteria with UDP- N-acetylmannosamine (UDP-ManNAc), the activated donor of ManNAc residues. Also involved in bacteriophage N4 adsorption.
  
  
 0.965
wzyE
Putative ECA polysaccharide chain elongation protein; Probably involved in the polymerization of enterobacterial common antigen (ECA) trisaccharide repeat units. Required for the assembly of the phosphoglyceride-linked form of ECA (ECA(PG)) and the water-soluble cyclic form of ECA (ECA(CYC)). Belongs to the WzyE family.
  
  
 0.965
wzxE
O-antigen translocase; Mediates the transbilayer movement of Und-PP-GlcNAc-ManNAcA- Fuc4NAc (lipid III) from the inner to the outer leaflet of the cytoplasmic membrane during the assembly of enterobacterial common antigen (ECA). Required for the assembly of the phosphoglyceride-linked form of ECA (ECA(PG)) and the water-soluble cyclic form of ECA (ECA(CYC)). Could also mediate the translocation of Und-PP-GlcNAc.
  
  
 0.954
rffG
dTDP-glucose 4,6-dehydratase; Catalyzes the dehydration of dTDP-D-glucose to form dTDP-6- deoxy-D-xylo-4-hexulose via a three-step process involving oxidation, dehydration and reduction; Belongs to the NAD(P)-dependent epimerase/dehydratase family. dTDP-glucose dehydratase subfamily.
  
  
 0.929
wzxB
Putative polisoprenol-linked O-antigen transporter; May be involved in the translocation process of the nascent O-polysaccharide molecules and/or its ligation to lipid A core units.
     
 0.877
wecG
UDP-N-acetyl-D-mannosaminuronic acid transferase; Catalyzes the synthesis of Und-PP-GlcNAc-ManNAcA (Lipid II), the second lipid-linked intermediate involved in enterobacterial common antigen (ECA) synthesis.
  
  
 0.857
wecE
TDP-4-oxo-6-deoxy-D-glucose transaminase; Catalyzes the synthesis of dTDP-4-amino-4,6-dideoxy-D- galactose (dTDP-Fuc4N) from dTDP-4-keto-6-deoxy-D-glucose (dTDP-D- Glc4O) and L-glutamate.
  
  
 0.849
wecF
TDP-Fuc4NAc:lipidIIFuc4NAc transferase; Catalyzes the synthesis of Und-PP-GlcNAc-ManNAcA-Fuc4NAc (Lipid III), the third lipid-linked intermediate involved in ECA synthesis; Belongs to the glycosyltransferase 56 family.
