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

Predicted Functional Partners:
hinT
Purine nucleoside phosphoramidase, dadA activator protein; Hydrolyzes purine nucleotide phosphoramidates, including adenosine 5'monophosphoramidate (AMP-NH2), adenosine 5'monophosphomorpholidate (AMP-morpholidate), guanosine 5'monophosphomorpholidate (GMP-morpholidate) and tryptamine 5'guanosine monophosphate (TpGd). Hydrolyzes lysyl-AMP (AMP-N-epsilon-(N-alpha-acetyl lysine methyl ester)) generated by lysine--tRNA ligase, and lysyl-GMP (GMP-N-epsilon-(N- alpha-acetyl lysine methyl ester)). Is essential for the activity of the enzyme D-alanine dehydrogenase (DadA) and is required for E [...]

lpoB
OM lipoprotein stimulator of MrcB transpeptidase; Regulator of peptidoglycan synthesis that is essential for the function of penicillin-binding protein 1B (PBP1b). Stimulates transpeptidase and transglycosylase activities of PBP1b in vitro. May also contribute to outer membrane constriction during cell division, in complex with PBP1b.
  
  
 0.979
ycfP
Putative UPF0227 family esterase.
  
  
 0.961
thiK
Thiamine kinase; Catalyzes the phosphorylation of thiamine to thiamine phosphate.
  
  
 0.942
nagZ
Beta N-acetyl-glucosaminidase; Plays a role in peptidoglycan recycling by cleaving the terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptide- linked peptidoglycan fragments, giving rise to free GlcNAc, anhydro-N- acetylmuramic acid and anhydro-N-acetylmuramic acid-linked peptides. Cleaves GlcNAc linked beta-1,4 to MurNAc tripeptides.
  
  
 0.883
ychJ
UPF0225 family protein.
      
 0.717
ybbN
DnaK co-chaperone, thioredoxin-like protein; Chaperedoxin that combines a chaperone activity with a redox- protective function. Involved in the protection against hypochlorous acid (HOCl), the active ingredient of bleach, which kills bacteria by causing protein aggregation. Functions as an efficient holdase chaperone that protects the substrates of the major folding systems GroEL/GroES and DnaK/DnaJ/GrpE from aggregation. In addition, it prevents the irreversible oxidation of its substrates through the formation of mixed disulfide complexes. After bleach stress, it transfers its substr [...]

sppA
Protease IV (signal peptide peptidase); Digests cleaved signal peptides in vitro, its in vivo function is unknown. This activity is necessary to maintain proper secretion of mature proteins across the membrane. Belongs to the peptidase S49 family.
