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.

yfbEPutative DegT/DnrJ/EryC1/StrS family; Catalyzes the conversion of UDP-4-keto-arabinose (UDP-Ara4O) to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides (By similarity); Belongs to the DegT/DnrJ/EryC1 family. ArnB subfamily. (385 aa)    
Predicted Functional Partners:
pmrF
Putative glycosyl transferase; Catalyzes the transfer of 4-deoxy-4-formamido-L-arabinose from UDP to undecaprenyl phosphate. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides. Plays an important role in pathogenesis by providing resistance to antimicrobial peptides within macrophages or at other anatomic sites encountered during infection. Belongs to the glycosyltransferase 2 family.
  
 0.999
yfbG
Putative transformylase; Bifunctional enzyme that catalyzes the oxidative decarboxylation of UDP-glucuronic acid (UDP-GlcUA) to UDP-4-keto- arabinose (UDP-Ara4O) and the addition of a formyl group to UDP-4- amino-4-deoxy-L-arabinose (UDP-L-Ara4N) to form UDP-L-4-formamido- arabinose (UDP-L-Ara4FN). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides (By similarity); In the N-terminal section; belongs to the Fmt family. UDP- L-Ara4N formyltransferase subfamily.
 
 0.999
pqaB
Putative melittin resistance protein; Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides. Belongs to the glycosyltransferase 83 family.
 
  
 0.989
arnE
Putative inner membrane protein; Translocates 4-amino-4-deoxy-L-arabinose-phosphoundecaprenol (alpha-L-Ara4N-phosphoundecaprenol) from the cytoplasmic to the periplasmic side of the inner membrane; Belongs to the ArnE family.
 
  
 0.988
arnD
Putative cytoplasmic protein; Catalyzes the deformylation of 4-deoxy-4-formamido-L- arabinose-phosphoundecaprenol to 4-amino-4-deoxy-L-arabinose- phosphoundecaprenol. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides (Probable).
 
  
 0.984
arnF
Putative inner membrane protein; Translocates 4-amino-4-deoxy-L-arabinose-phosphoundecaprenol (alpha-L-Ara4N-phosphoundecaprenol) from the cytoplasmic to the periplasmic side of the inner membrane.
  
  
 0.976
basR
Response regulator in two-component regulatory system with BasS; Member of the two-component regulatory system BasS/BasR. BasR induces the transcription of the ugd, ais, arnBCADTEF and eptA-basRS loci, all involved in resistance to polymyxin. Represses the transcription of pmrD. Plays a role in the adaptation of the organism to the host environment, in particular to neutrophils, and therefore it plays a role in virulence as well.
   
  
 0.946
yjdB
Putative integral membrane protein; Catalyzes the addition of a phosphoethanolamine moiety to the lipid A. The phosphoethanolamine modification is required for resistance to polymyxin; Belongs to the phosphoethanolamine transferase family. EptA subfamily.
   
  
 0.928
rfbP
Undecaprenol-phosphate galactosephosphotransferase, and; Is responsible for transferring galactose-1-phosphate to the lipid precursor undecaprenol phosphate in the first steps of O- polysaccharide biosynthesis; Belongs to the bacterial sugar transferase family.
  
 0.904
phoQ
Sensory kinase protein in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ which regulates the expression of genes involved in virulence, adaptation to acidic and low Mg(2+) environments and resistance to host defense antimicrobial peptides. Essential for intramacrophage survival of S.typhimurium. In low periplasmic Mg(2+), PhoQ functions as a membrane- associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of [...]
