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

lysXLysyl-tRNA synthetase 2 LysX; Catalyzes the production of L-lysyl-tRNA(Lys)transfer and the transfer of a lysyl group from L-lysyl-tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), one of the components of the bacterial membrane with a positive net charge. LPG synthesis contributes to the resistance to cationic antimicrobial peptides (CAMPs) and likely protects M.tuberculosis against the CAMPs produced by competiting microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with positively charged L-lys [...] (1172 aa)    
Predicted Functional Partners:
ileS
Isoleucyl-tRNA synthetase IleS; 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) (By similarity).

lysS
Lysyl-tRNA synthetase 1 LysS (lysine--tRNA ligase 1) (LysRS 1) (lysine translase); Rv3598c, (MTCY07H7B.24), len: 505 aa. Probable lysS,lysyl-tRNA synthetase 1, equivalent to P46861|SYK_MYCLE|LYSS|ML0233 lysyl-tRNA synthetase from Mycobacterium leprae (507 aa), FASTA scores: opt: 2835,E(): 4.5e-172, (85.45% identity in 501 aa overlap); and similar with C-terminal part of Q9CC23|LYSX|ML1393 C-term lysyl-tRNA synthase from Mycobacterium leprae (1039 aa) FASTA scores: opt: 1257, E(): 7.6e-72, (44.55% identity in 505 aa overlap). Also similar to others e.g. P37477|SYK_BACSU|LYSS from Bacill [...]

gltS
Glutamyl-tRNA synthetase GltS (glutamate--tRNA ligase) (glutamyl-tRNA synthase) (GLURS); 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).
  
 0.910
guaA
Probable GMP synthase [glutamine-hydrolyzing] GuaA (glutamine amidotransferase) (GMP synthetase); Catalyzes the synthesis of GMP from XMP.
  
  
 0.906
leuS
Probable leucyl-tRNA synthetase LeuS (leucine--tRNA ligase) (LEURS); Rv0041, (MTCY21D4.04), len: 969 aa. Probable leucyl-tRNA synthetase, similar to many. Contains PS00178 Aminoacyl-transfer RNA synthetases class-I signature. Belongs to class-I aminoacyl-tRNA synthetase family.
  
 0.894
mesJ
Possible cell cycle protein MesJ; Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. Belongs to the tRNA(Ile)-lysidine synthase family.
  
 
 0.890
proS
Proline--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 [...]
  
 0.883
metS
Methionyl-tRNA synthetase MetS (MetRS) (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. MetG type 2B subfamily.
  
 0.880
serS
SERYL-tRNA synthetase SerS (serine--tRNA ligase) (SERRS) (serine translase); Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec).

prfB
Probable peptide chain release factor 2 PrfB (RF-2); Peptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA.
