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; Alternative locus ID: PGP2_1467. (426 aa)    
Predicted Functional Partners:
hisI
Phosphoribosyl-AMP cyclohydrolase; Alternative locus ID: PGP2_1423; Phosphoribosyl-ATP pyrophosphatasee; In the N-terminal section; belongs to the PRA-CH family.
  
 
 0.918
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
aspS
Aspartyl-tRNA synthetase Aspartyl-tRNA(Asn) 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.
 
  
 0.733
EU91_0117
Hypothetical protein; Alternative locus ID: PGP2_1466; FIG01150737: hypothetical protein.
       0.660
pheT
Phenylalanyl-tRNA synthetase beta chain; Alternative locus ID: PGP2_1268; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
 
  
 0.654
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.614
EU91_0120
Hypothetical protein; Alternative locus ID: PGP2_1469; Tryptophan-rich protein DUF2389; Ssr2843 homolog.
       0.599
EU91_0932
ATP phosphoribosyltransferase regulatory subunit; Alternative locus ID: PGP2_1238.
  
     0.592
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).
  
 
 0.590
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).
  
 
 0.586
