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

hisSKEGG: csc:Csac_0676 histidyl-tRNA synthetase; TIGRFAM: histidyl-tRNA synthetase; PFAM: tRNA synthetase class II (G H P and S); Anticodon-binding domain protein. (421 aa)    
Predicted Functional Partners:
aspS
aspartyl-tRNA synthetase; Catalyzes the attachment of L-aspartate to tRNA(Asp) in a two-step reaction: L-aspartate is first activated by ATP to form Asp- AMP and then transferred to the acceptor end of tRNA(Asp). Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
 
  
 0.976
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.
 
 
 0.909
leuS
TIGRFAM: leucyl-tRNA synthetase; KEGG: csc:Csac_1819 leucyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 0.822
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).
  
 
 0.803
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.
 
 
 0.800
serS
seryl-tRNA synthetase; Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec).
 
 
 0.792
ileS
isoleucyl-tRNA synthetase; 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 1 subfamily.
 
  
 0.773
cysS
TIGRFAM: cysteinyl-tRNA synthetase; PFAM: Cysteinyl-tRNA synthetase class Ia; Cysteinyl-tRNA synthetase class Ia DALR; tRNA synthetase class I (M); KEGG: csc:Csac_0708 cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.755
hisI
TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: phosphoribosyl-AMP cyclohydrolase; phosphoribosyl-ATP pyrophosphohydrolase; KEGG: csc:Csac_2019 bifunctional phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphatase protein; In the N-terminal section; belongs to the PRA-CH family.
  
  
 0.734
guaA
GMP synthase, large subunit; Catalyzes the synthesis of GMP from XMP.
  
  
 0.712
