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

ybbKConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function. (151 aa)    
Predicted Functional Partners:
ybbJ
Putative acyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
  
 0.995
pupG
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.
      0.900
ddl
D-alanyl-D-alanine ligase A; Cell wall formation.
 
    0.888
ycsE
Putative phosphatase; Catalyzes the dephosphorylation of the riboflavin precursor 5-amino-6-(5-phospho-D-ribitylamino)uracil and of flavin mononucleotide (FMN) in vitro. To a lesser extent, may also catalyze the dephosphorylation of a broad range of substrates such as phosphorylated sugars and triphosphate nucleotides in vitro.
 
      0.790
murQ
D-lactyl ether N-acetylmuramic-6-phosphate acid etherase; Specifically catalyzes the cleavage of the D-lactyl ether substituent of MurNAc 6-phosphate, producing GlcNAc 6-phosphate and D- lactate.
  
    0.743
pth
peptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.
      0.713
ybbH
Putative transcriptional regulator; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator.
 
    0.665
thiI
Putative persulfide ATP pyrophosphatase involved in thiamine biosynthesis and tRNA modification; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS.
 
     0.562
ybbF
Putative PTS system EIIBC component ybbF; 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.
  
    0.495
yccK
Putative ion channel associated enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the aldo/keto reductase family. Aldo/keto reductase 2 subfamily.
