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

mtrAPutative two-component response regulator; Member of the two-component regulatory system MtrA/MtrB. (228 aa)    
Predicted Functional Partners:
mtrB
Putative two-component system sensor kinase; Member of the two-component regulatory system MtrA/MtrB. Seems to function as a membrane-associated protein kinase that phosphorylates MtrA in response to environmental signals (By similarity).
 0.999
ML2124
Sensor histidine kinase; Member of the two-component regulatory system PrrB/PrrA that is involved specifically in early intracellular multiplication of Mycobacterium and is essential for its viability. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of PrrA. In turn, PrrA binds to the upstream promoter regions of target genes including itself to positively regulate their expression.

ML2440
Probable two-component system sensor histidine kinase; Probably forms part of a two-component regulatory system SenX3/RegX3. Phosphorylates RegX3 (Probable).

lpqB
Putative lipoprotein; Similar to Mycobacterium tuberculosis putative lipoprotein RV3244C OR MTCY20B11.19C TR:O05889 (EMBL:Z95121) fasta scores: E(): 0, 87.9% id in 579 aa, and to Streptomyces coelicolor putative lipoprotein SCE33.13C TR:CAB90922 (EMBL:AL355774) fasta scores: E(): 0.00039, 24.4% id in 624 aa. Contains a probable N-terminal signal sequence. Contains PS00013 Prokaryotic membrane lipoprotein lipid attachment site.
     
 0.891
ML0175
Putative two-component system sensor kinase; Member of the two-component regulatory system MprB/MprA which contributes to maintaining a balance among several systems involved in stress resistance and is required for establishment and maintenance of persistent infection in the host. In response to environmental signals MprB acts as both a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to MprA, and a protein phosphatase that dephosphorylates phospho-MprA (By similarity).

tmk
Putative thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.
       0.741
sahH
Putative S-adenosyl-L-homocysteine hydrolase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
       0.698
ML0397
Putative transporter protein; C-terminal half is similar to sugar permeases e.g. Escherichia coli AraH, L-arabinose transport system permease protein, SW:ARAH_ECOLI (P08532) (329 aa); Fasta score E(): 1.1e-26, 36.0% identity in 297 aa overlap. The N-terminal half shows weak similarity to other proteins containing PAS and DUF9 domains. There is a possiblity that this is a signal transduction protein. Previously sequenced as TR:Q49739 (EMBL:U00015) (577 aa); Fasta score E(): 0, 99.8% identity in 577 aa overlap. Contains hydrophobic, possible membrane-spanning regions in the C-terminal ha [...]

dnaA
Putative chromosomal replication initiator protein; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids (By similarity).
  
  
 0.530
ML1439
Conserved hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. Belongs to the RNA polymerase-binding protein RbpA family.
