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

Score
HisSPutative histidine--tRNA ligase; KEGG: lxx:Lxx17220 1.3e-74 hisS; histidyl-tRNA synthetase K01892; COG: COG0124 Histidyl-tRNA synthetase; Psort location: Cytoplasmic, score: 10.00; Belongs to the class-II aminoacyl-tRNA synthetase family. (423 aa)    
Predicted Functional Partners:
aspS
aspartate--tRNA ligase; 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.
  
  
 0.933
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. Short subfamily.
 
 
 0.910
hemZ
KEGG: cpe:CPE1935 9.2e-90 hemZ; probable coproporphyrinogen III oxidase K02495; COG: COG0635 Coproporphyrinogen III oxidase and related Fe-S oxidoreductases; Psort location: Cytoplasmic, score: 9.98.
       0.843
aspS-2
aspartate--tRNA ligase; 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.
  
  
 0.815
hisE
phosphoribosyl-ATP diphosphatase; KEGG: sao:SAOUHSC_03008 3.6e-56 imidazole glycerol phosphate synthase subunit HisF, putative K01663; COG: COG0139 Phosphoribosyl-AMP cyclohydrolase; Psort location: Cytoplasmic, score: 9.98; In the C-terminal section; belongs to the PRA-PH family.
 
  
 0.802
thrS
threonine--tRNA ligase; 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).
  
 
 0.788
secD
Export membrane protein SecD; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. SecDF uses the proton motive force (PMF) to complete protein translocation after the ATP-dependent function of SecA; Belongs to the SecD/SecF family. SecD subfamily.
 
  
 0.769
valS
valine--tRNA ligase; 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.
  
 
 0.722
EDS07667.1
Metallo-beta-lactamase domain protein; KEGG: ctc:CTC02196 7.7e-38 hydroxyacylglutathione hydrolase K01069; COG: COG0491 Zn-dependent hydrolases, including glyoxylases; Psort location: Cytoplasmic, score: 8.87.
  
    0.715
ileS
isoleucine--tRNA ligase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 2 subfamily.
