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

alaSalanyl-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. (888 aa)    
Predicted Functional Partners:
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.

DIP1349
Conserved hypothetical protein; Could be a nuclease involved in processing of the 5'-end of pre-16S rRNA; Belongs to the YqgF nuclease family.
  
  
 0.908
DIP1177
Conserved hypothetical protein; C-terminal region similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1730 SWALL:AAK45999 (EMBL:AE007035) (250 aa) fasta scores: E(): 4e-32, 47.73% id in 243 aa, and to Streptomyces coelicolor hypothetical 22.8 kDa protein SCI51.30c SWALL:Q9S210 (EMBL:AL109848) (210 aa) fasta scores: E(): 3.1e-24, 49.17% id in 181 aa.
   
 0.906
DIP2341
Putative integral membrane transport protein; Similar to Escherichia coli O157:H7 putative transporter ECS3800 SWALL:BAB37223 (EMBL:AP002563) (192 aa) fasta scores: E(): 6e-15, 30.16% id in 179 aa. Lies alongside a putative ABC transporter ATP-binding subunit.
   
 0.906
aspS
aspartyl-tRNA 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.
 
  
 0.873
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.

DIP2130
Full length similarity to Streptococcus pneumoniae phosphoribosylformylglycinamidine synthase, putative SP0045 TR:AAK74234 (EMBL:AE007322) (1241 aa) fasta scores: E(): 7.8e-167, 47.73% id in 1259 aa. Second two thirds similar to many others e.g. Mycobacterium tuberculosis phosphoribosylformylglycinamidine synthase II PurL or Rv0803 or MT0823 or MTCY07H7A.06c SW:PURL_MYCTU (P54876) (754 aa) fasta scores: E(): 8.3e-22, 26.35% id in 740 aa.
  
    0.736
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.
  
 
 0.728
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).
  
 
 0.706
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.
