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

Score
alaSProbable alanyl-tRNA synthetase AlaS (alanine--tRNA ligase) (alanine translase) (ALARS); Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain; Belongs to the class-II aminoacyl-tRNA synthetase family. (904 aa)    
Predicted Functional Partners:
Rv2554c
Conserved protein; Could be a nuclease involved in processing of the 5'-end of pre-16S rRNA.

pheT
Rv1650, (MTCY06H11.15), len: 831 aa. Probable pheT,Phenylalanyl-tRNA synthetase beta chain, similar to several e.g. SYFB_ECOLI|P07395 from Escherichia coli (795 aa),FASTA scores: opt: 995, E(): 0, (31.8% identity in 847 aa overlap). Belongs to the phenylalanyl-tRNA synthetase beta chain family - subfamily 1.
 
 
 0.969
mltG
Probable conserved membrane protein; Functions as a peptidoglycan terminase that cleaves nascent peptidoglycan strands endolytically to terminate their elongation. Belongs to the transglycosylase MltG family.
  
    0.939
Rv1691
Rv1691, MTCI125.13, len: 250 aa. Conserved hypothetical protein, similar to Q9S210|SCI51.30C|AL109848 Hypothetical protein from Streptomyces coelicolor (210 aa),FASTA score: opt: 556, E(): 6.4e-27, (50.6% identity in 180 aa overlap).
  
 0.925
stf3
Conserved hypothetical protein; Required for the sulfation of S881. S881 is a sulfated menaquinone, which is localized in the outer envelope of M.tuberculosis and negatively regulates its virulence. 3'-phosphoadenosine-5'- phosphosulfate (PAPS) is the sulfate donor. Belongs to the Stf3 family.

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.
  
 
 0.877
thrS
Probable threonyl-tRNA synthetase ThrS (threonine-tRNA synthetase)(ThrRS) (threonine-tRNA ligase); Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged L-seryl-tRNA(Thr).

PE_PGRS12
PE-PGRS family protein PE_PGRS12; Rv0832, (MTV043.24), len: 137 aa. PE_PGRS12, Member of the Mycobacterium tuberculosis PE family, possibly PGRS subfamily of gly-rich proteins (see citation below), highly similar to many others e.g. MTCY1A11.25c|Z78020 (498 aa),FASTA scores: opt: 529, E(): 5.2e-22, (61.8% identity in 136 aa overlap); etc. Appears to have incurred frameshift as next ORF should be continuation; sequence has been checked but no error found.
