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

KOO44360.1histidine--tRNA ligase; Catalyzes a two-step reaction, first charging a histidine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; class II aminoacyl-tRNA synthetase; forms homodimers; some organisms have a paralogous gene, hisZ, that is similar to hisS and produces a protein that performs the first step in histidine biosynthesis along with HisG; Derived by automated computational analysis using gene prediction method: Protein Homology. (423 aa)    
Predicted Functional Partners:
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.
  
 0.906
hisI
phosphoribosyl-ATP pyrophosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology; In the N-terminal section; belongs to the PRA-CH family.
  
 
 0.890
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.
  
  
 0.800
thrS
threonyl-tRNA synthase; 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).
 
 
 0.695
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.664
ispG
4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase; Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME- 2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate. Belongs to the IspG family.
  
  
 0.619
cysS
cysteinyl-tRNA synthetase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.618
prs
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily.
    
 0.592
secD
Preprotein translocase subunit 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.
  
  
 0.590
pheT
phenylalanyl-tRNA synthase subunit beta; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
