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

PE23Rv2328, (MTCY3G12.06), len: 382 aa. PE23, Member of the Mycobacterium tuberculosis PE family (see citation below), similar to others e.g. Q9L8K5|MAG24-1 PE-PGRS homolog from Mycobacterium marinum (638 aa), FASTA scores: opt: 495, E(): 6.6e-18, (34.65% identity in 401 aa overlap); etc. (382 aa)    
Predicted Functional Partners:
Rv2133c
Rv2133c, (MTCY270.35), len: 262 aa. Conserved hypothetical protein. Function: unknown but equivalent to hypothetical Mycobacterium leprae protein, Q49774. FASTA best: Q49774 B2126_C1_150 (262 aa) opt: 1447, E(): 0; (79.0% identity in 262 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

alaS
Probable 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.
  
 0.848
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.
   
 0.817
helZ
Probable helicase HelZ; Rv2101, (MTV020.01), len: 1013 aa. Probable helZ,helicase, similar to many. Nucleotide position 2361623 in the genome sequence has been corrected, A:C resulting in M462L.
   
 0.779
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).
   
 0.778
Rv3529c
Rv3529c, (MTCY03C7.27), len: 384 aa. Conserved hypothetical protein, showing some similarity to Q50695|YM67_MYCTU|Rv2267c|MT2329|MTCY339.43 hypothetical 46.1 KDA protein from Mycobacterium tuberculosis (388 aa) FASTA scores: opt: 261, E(): 1.6e-09, (27.25% identity in 253 aa overlap).
   
 0.778
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 0.747
rplJ
50S ribosomal protein L10 RplJ; Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors.
   
 0.746
rplF
50S ribosomal protein L6 RplF; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.
    
  0.743
rpmD
Rv0722, (MTCY210.41), len: 65 aa. rpmD, 50S ribosomal protein L30, equivalent to O33001 ribosomal protein L30 from Mycobacterium leprae (71 aa). Also highly similar to others e.g. P46789|RL30_STRCO 50S ribosomal protein L30 from Streptomyces coelicolor (60 aa); P02430|RL30_ECOLI 50S ribosomal protein L30 from Escherichia coli (58 aa), FASTA scores: opt: 168, E(): 1.5e-13, (53.7% identity in 54 aa overlap); etc. Belongs to the L30P family of ribosomal proteins.
