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.

hisShistidyl-tRNA synthetase; Similar to Mycobacterium tuberculosis histidyl-tRNA synthetase HisS or Rv2580c or MT2657 or MTCY227.21 SWALL:SYH_MYCTU (SWALL:Q50641) (423 aa) fasta scores: E(): 1.6e-112, 70.4% id in 419 aa, and to Bacillus subtilis histidyl-tRNA synthetase HisS SWALL:SYH_BACSU (SWALL:O32039) (424 aa) fasta scores: E(): 3.8e-61, 45.63% id in 412 aa. (423 aa)    
Predicted Functional Partners:
aspS
aspartyl-tRNA synthetase; Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
  
  
 0.840
hisG
ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
  
 
 0.810
pheT
Similar to Mycobacterium tuberculosis phenylalanyl-tRNA synthetase beta chain PheT or Rv1650 or MT1688 or MTCY06H11.15 SWALL:SYFB_MYCTU (SWALL:P94985) (831 aa) fasta scores: E(): 4.2e-156, 49.64% id in 844 aa, and to Bacillus subtilis phenylalanyl-tRNA synthetase beta chain PheT SWALL:SYFB_BACSU (SWALL:P17922) (804 aa) fasta scores: E(): 1.8e-53, 30.69% id in 847 aa.
  
  
 0.802
DIP1361
Conserved hypothetical protein; Similar to Streptomyces coelicolor possible hydrolase SC9C5.33c SWALL:Q9KXP1 (EMBL:AL357523) (235 aa) fasta scores: E(): 6.5e-25, 40.35% id in 223 aa, and to Escherichia coli hypothetical protein YcbL or B0927 SWALL:YCBL_ECOLI (SWALL:P75849) (215 aa) fasta scores: E(): 3.7e-23, 36.79% id in 212 aa.
  
    0.752
tpx
Thiol peroxidase; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. Tpx subfamily.
       0.750
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 1 subfamily.
 
 
 0.682
thrS
threonyl-tRNA synthetase; Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged L-seryl-tRNA(Thr).
  
 
 0.660
guaA
GMP synthase [glutamine-hydrolysing]; Catalyzes the synthesis of GMP from XMP.
  
  
 0.649
DIP1552
Putative glycogen phosphorylase; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.
      
 0.640
ruvB
Holliday junction DNA-helicase; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing.
