STRINGSTRING
proS protein (Synechococcus elongatus PCC7942) - STRING interaction network
"proS" - Proline--tRNA ligase in Synechococcus elongatus PCC7942
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

proSProline--tRNA ligase; 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 deacy [...] (606 aa)    
Predicted Functional Partners:
ileS
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) (954 aa)

metG
Methionine--tRNA ligase; 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 (525 aa)
   
 
  0.791
valS
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 (909 aa)

guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP (575 aa)
   
        0.723
gltX
Glutamate--tRNA ligase; 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) (481 aa)
 
 
  0.698
aspS
Aspartate--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 (599 aa)
