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
valSvalyl-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. (919 aa)    
Predicted Functional Partners:
leuS
Similar to Escherichia coli leucyl-tRNA synthetase LeuS or B0642 SWALL:SYL_ECOLI (SWALL:P07813) (860 aa) fasta scores: E(): 1.9e-37, 37.53% id in 967 aa, and to Streptomyces coelicolor leucyl-tRNA synthetase LeuS SWALL:Q9RDL5 (EMBL:AL136518) (966 aa) fasta scores: E(): 1.6e-209, 59.93% id in 971 aa; Belongs to the class-I aminoacyl-tRNA synthetase family.

DIP1785
Mur ligase family protein; Similar to Mycobacterium tuberculosis folylpolyglutamate synthase Rv2447c TR:O53174 (EMBL:AL021246) (487 aa) fasta scores: E(): 1.2e-100, 57.46% id in 496 aa, and to Mycobacterium leprae folylpolyglutamate synthase ML1471 TR:Q9CBY8 (EMBL:AL583922) (485 aa) fasta scores: E(): 3.8e-96, 56.17% id in 470 aa.

argS
arginyl-tRNA synthetase; Similar to Mycobacterium tuberculosis arginyl-tRNA synthetase ArgS or Rv1292 or MT1331 or MTCY373.12 SW:SYR_MYCTU (Q10609) (550 aa) fasta scores: E(): 4.5e-144, 65.63% id in 550 aa, and to Bacillus subtilis arginyl-tRNA synthetase ArgS SW:SYR_BACSU (P46906) (556 aa) fasta scores: E(): 1.7e-82, 42.75% id in 545 aa.

DIP1784
Putative membrane protein; Similar to Mycobacterium tuberculosis hypothetical protein Rv2446c TR:O53173 (EMBL:AL021246) (123 aa) fasta scores: E(): 1.5e-07, 31.35% id in 118 aa, and to Mycobacterium leprae conserved membrane protein ML1470 TR:Q9CBY9 (EMBL:AL583922) (123 aa) fasta scores: E(): 4.9e-07, 30.46% id in 128 aa.

guaA
GMP synthase [glutamine-hydrolysing]; Catalyzes the synthesis of GMP from XMP.
  
  
 0.846
alaS
alanyl-tRNA synthetase; Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.
 
  
 0.838
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 2 subfamily.
  
 
0.837
mdh
Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate. Belongs to the LDH/MDH superfamily. MDH type 2 family.
  
    0.822
pheT
Similar to Mycobacterium tuberculosis phenylalanyl-tRNA synthetase beta chain PheT or Rv1650 or MT1688 or MTCY06H11.15 SWALL:SYFB_MYCTU (SWALL:P94985) (831 aa) fasta scores: E(): 4.2e-156, 49.64% id in 844 aa, and to Bacillus subtilis phenylalanyl-tRNA synthetase beta chain PheT SWALL:SYFB_BACSU (SWALL:P17922) (804 aa) fasta scores: E(): 1.8e-53, 30.69% id in 847 aa.

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).
