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

lysSAppears to be a gene fusion. N-terminal region similar to Streptomyces coelicolor putative integral membrane protein SC3C8.03c TR:O69916 (EMBL:AL023861) (589 aa) fasta scores: E(): 4.3e-57, 37.26% id in 577 aa. C-terminal region similar to Thermus aquaticus lysyl-tRNA synthetase LysS SW:SYK_THETH (P41255) (492 aa) fasta scores: E(): 9.8e-57, 40.8% id in 446 aa; Belongs to the class-II aminoacyl-tRNA synthetase family. (1049 aa)    
Predicted Functional Partners:
lysU
Putative lysyl-tRNA synthetase; Similar to Escherichia coli heat inducible lysyl-tRNA synthetase LysU SW:SYK2_ECOLI (P14825) (504 aa) fasta scores: E(): 4.5e-73, 40.8% id in 522 aa, and to Mycobacterium tuberculosis lysyl-tRNA synthetase 1 Rv3598c SW:SYK1_MYCTU (O06284) (505 aa) fasta scores: E(): 3.9e-118, 61.87% id in 522 aa; Belongs to the class-II aminoacyl-tRNA synthetase family.

ptsG
Similar to Corynebacterium glutamicum PTS system, glucose-specific IIABC component PtsG SWALL:PTGA_CORGL (SWALL:Q45298) (674 aa) fasta scores: E(): 2.8e-59, 44.91% id in 688 aa, and to Staphylococcus xylosus PTS system, sucrose-specific IIBC component ScrA SWALL:PTSB_STAXY (SWALL:P51184) (480 aa) fasta scores: E(): 8e-26, 27.73% id in 494 aa.

guaA
GMP synthase [glutamine-hydrolysing]; Catalyzes the synthesis of GMP from XMP.
  
  
 0.845
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.
  
 0.792
metG
methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
  
 0.771
proS
prolyl-tRNA synthetase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves dea [...]

fusA
Elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF-2 subfamily.
 
  
 0.768
prfB
Peptide chain release factor 2; Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA.
  
 
 0.764
gluQ
Putative glutamyl-tRNA synthetase; Catalyzes the tRNA-independent activation of glutamate in presence of ATP and the subsequent transfer of glutamate onto a tRNA(Asp). Glutamate is transferred on the 2-amino-5-(4,5-dihydroxy-2- cyclopenten-1-yl) moiety of the queuosine in the wobble position of the QUC anticodon; Belongs to the class-I aminoacyl-tRNA synthetase family. GluQ subfamily.

gltX
glutamyl-tRNA synthetase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu); Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily.
