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.

metGmethionyl-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. (629 aa)    
Predicted Functional Partners:
leuS
leucyl-tRNA synthetase; Similar to PID:1652380 percent identity: 69.10; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 0.994
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 [...]

argS
arginyl-tRNA synthetase; Similar to SP:P46906 PID:971336 PID:2224756 GB:AL009126 percent identity: 67.62; identified by sequence similarity; putative.
 
 0.988
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 1 subfamily.
 
0.987
fmt
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
  
 
 0.984
pheS
phenylalanyl-tRNA synthetase, alpha subunit; Similar to GB:AL009126 percent identity: 73.25; identified by sequence similarity; putative; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily.
  
 0.984
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
    
 0.981
aar
Cystathionine gamma-synthase; Catalyzes the racemization of L-alanine to D-alanine, and of L-glutamate to D-glutamate. The activity is low, but likely physiological since T.maritima lacks canonical alr and murI genes, while D-alanine and D-glutamate are essential components of peptidoglycan. Also displays a more efficient cystathionine beta-lyase (CBL) activity, cleaving cystathionine to homocysteine and pyruvate; however, this reaction seems not to be physiologically relevant since T.maritima possesses an O-acetyl-homoserine thiolase (MetY) that bypasses the need of CBL for methionine [...]

TM_0268
5-methyltetrahydrofolate S-homocysteine methyltransferase; Similar to GB:U00017 PID:466997 percent identity: 54.29; identified by sequence similarity; putative.
  
 
 0.973
gltX1
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.
