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. (878 aa)    
Predicted Functional Partners:
yvyF
Putative regulator of flagella formation; May be involved in the assembly, structure, or function of the flagellum. May polymerize to form a filamentous structure that is part of the flagellum.

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.
  
 0.940
valS
valyl-tRNA synthetase; 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 (By similarity). Catalyzes the attachment of valine to tRNA(Val); Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.

pheT
phenylalanyl-tRNA synthetase (beta subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.

smpB
tmRNA-binding protein; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches t [...]

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).
 
 
 0.865
yrrK
Putative Holliday junction resolvase; Could be a nuclease involved in processing of the 5'-end of pre-16S rRNA.
  
  
 0.863
leuS
leucyl-tRNA synthetase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 0.860
metS
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; Belongs to the class-I aminoacyl-tRNA synthetase family. MetG type 2B subfamily.
  
  
 0.857
secDF
Protein-export membrane protein; Required for efficient translocation of secretory pre- proteins under conditions of hypersecretion but is not required for the release of mature proteins from the membrane. In the N-terminal section; belongs to the SecD/SecF family. SecD subfamily.
