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

thiIHypothetical thiamine biosynthesis protein thiI; 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. (469 aa)    
Predicted Functional Partners:
PTO1061
Molybdenum cofactor biosynthesis protein C.
  
  
 0.990
PTO0521
Molybdopterin biosynthesis MoeB protein.
     
 0.987
thiE
Thiamin-phosphate pyrophosphorylase; Condenses 4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP). Belongs to the thiamine-phosphate synthase family.
     
 0.969
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 2 subfamily.

PTO0409
Protein secretion chaperonin CsaA.
  
  
 0.933
PTO0874
methionyl-tRNA synthetase.
  
  
 0.933
PTO0429
Hypothetical oxidoreductase.
  
  
 0.929
PTO0152
ATPases of the PP-loop superamily.
  
  
 0.924
truA
tRNA pseudouridine synthase A; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs; Belongs to the tRNA pseudouridine synthase TruA family.
 
 
 0.921
ppa
Inorganic pyrophosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
