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. (610 aa)    
Predicted Functional Partners:
leuS
Similar to Escherichia coli leucyl-tRNA synthetase LeuS or B0642 SWALL:SYL_ECOLI (SWALL:P07813) (860 aa) fasta scores: E(): 1.9e-37, 37.53% id in 967 aa, and to Streptomyces coelicolor leucyl-tRNA synthetase LeuS SWALL:Q9RDL5 (EMBL:AL136518) (966 aa) fasta scores: E(): 1.6e-209, 59.93% id in 971 aa; Belongs to the class-I aminoacyl-tRNA synthetase family.

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.
  
 0.948
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 Mycobacterium tuberculosis arginyl-tRNA synthetase ArgS or Rv1292 or MT1331 or MTCY373.12 SW:SYR_MYCTU (Q10609) (550 aa) fasta scores: E(): 4.5e-144, 65.63% id in 550 aa, and to Bacillus subtilis arginyl-tRNA synthetase ArgS SW:SYR_BACSU (P46906) (556 aa) fasta scores: E(): 1.7e-82, 42.75% id in 545 aa.
  
 0.931
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.
     
 0.922
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
  
 
 0.908
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.

DIP0873
Conserved hypothetical protein; Similar to Corynebacterium glutamicum Mg-dependent DNAse CGL0908 SWALL:Q8NRY3 (EMBL:AP005276) (277 aa) fasta scores: E(): 3.7e-81, 73.74% id in 278 aa, and to Mycobacterium tuberculosis hypothetical protein Ycfh Rv1008 or MTCI237.25 TR:O08343 (EMBL:Z94752) (264 aa) fasta scores: E(): 4.4e-40, 44.61% id in 260 aa.

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.

lysS
Appears 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.
