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

hisShistidyl-tRNA synthetase; Identified by similarity to SP:O32422; match to protein family HMM PF00587; match to protein family HMM PF03129; match to protein family HMM TIGR00442. (415 aa)    
Predicted Functional Partners:
aspS-2
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.
 
  
 0.970
CPF_2191
Identified by match to protein family HMM PF00753.
  
    0.763
CPF_2190
Putative ferrochelatase; Identified by similarity to SP:P32396; match to protein family HMM PF04055.
       0.755
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).
  
 
 0.733
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.719
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.
 
 
 0.696
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).
 
 
 0.688
cysS
cysteinyl-tRNA synthetase; Identified by match to protein family HMM PF01406; match to protein family HMM PF09190; match to protein family HMM PF09334; match to protein family HMM TIGR00435; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.662
leuS
leucyl-tRNA synthetase; Identified by similarity to SP:P36430; match to protein family HMM PF00133; match to protein family HMM PF08264; match to protein family HMM PF09334; match to protein family HMM TIGR00396; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 0.661
relA
GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
