aspS protein (Alcaligenes faecalis) - STRING interaction network
"aspS" - Aspartate--tRNA(Asp/Asn) ligase in Alcaligenes faecalis
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
aspSAspartate--tRNA(Asp/Asn) ligase; 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 (595 aa)    
Predicted Functional Partners:
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B; Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp- tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl-tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp-tRNA(Asn) or phospho-Glu-tRNA(Gln); Belongs to the GatB/GatE family. GatB subfamily (485 aa)
Endonuclease; Derived by automated computational analysis using gene prediction method- Protein Homology (283 aa)
Translation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (1016 aa)
leucine--tRNA ligase; LeuRS; class-I aminoacyl-tRNA synthetase; charges leucine by linking carboxyl group to alpha-phosphate of ATP and then transfers aminoacyl-adenylate to its tRNA; due to the large number of codons that tRNA(Leu) recognizes, the leucyl-tRNA synthetase does not recognize the anticodon loop of the tRNA, but instead recognition is dependent on a conserved discriminator base A37 and a long arm; an editing domain hydrolyzes misformed products; in Methanothermobacter thermautotrophicus this enzyme associates with prolyl-tRNA synthetase; Derived by automated computational [...] (886 aa)
Isoleucine--tRNA ligase; 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) (946 aa)
Phenylalanine--tRNA ligase alpha subunit; Derived by automated computational analysis using gene prediction method- Protein Homology; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily (340 aa)
Valine--tRNA ligase; 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 (950 aa)
Elongation factor 4; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back- translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner (597 aa)
Membrane protein; Derived by automated computational analysis using gene prediction method- Protein Homology (219 aa)
Cardiolipin synthase B; Catalyzes the phosphatidyl group transfer from one phosphatidylglycerol molecule to another to form cardiolipin (CL) (diphosphatidylglycerol) and glycerol (413 aa)
