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
pknDTransmembrane serine/threonine-protein kinase D PknD (protein kinase D) (STPK D); Key microbial factor required for central nervous system tuberculosis. Required for invasion of host brain endothelia, but not macrophages, lung epithelia or other endothelia. Phosphorylates the anti-anti-sigma factor homolog Rv0516c, which inhibits binding of Rv0516c to Rv2638, another anti-anti-sigma factor. Can also phosphorylate the FHA domain of Rv1747. (664 aa)    
Predicted Functional Partners:
pstP
Phosphoserine/threonine phosphatase PstP; The only predicted protein phosphatase in M.tuberculosis, it dephosphorylates at least 5 protein kinases (PknA, PknB, PknD, PknE and PknF) and the penicillin-binding protein PBPA.
 
 
 0.903
pstS2
Periplasmic phosphate-binding lipoprotein PstS2 (PBP-2) (PstS2); Functions in inorganic phosphate uptake, although probably not the main uptake protein under phosphate starvation. Part of the ABC transporter complex PstSACB involved in phosphate import (Probable).
  
  
 0.878
Rv1747
Probable conserved transmembrane ATP-binding protein ABC transporter; Involved in the translocation of an unknown substrate across the membrane. Transmembrane domains (TMD) form a pore in the membrane and the ATP-binding domain (NBD) is responsible for energy generation. Required for virulence; In the C-terminal section; belongs to the ABC-2 integral membrane protein family.
  
 
 0.821
Rv0311
Unknown protein; Rv0311, (MTCY63.16), len: 409 aa. Unknown protein. Contains PS00881 Protein splicing signature.
   
  
 0.805
garA
Conserved protein with FHA domain, GarA; Involved in regulation of glutamate metabolism. Acts as a phosphorylation-dependent molecular switch that modulates the activities of Kgd, Gdh and GltB.
 
 
 0.799
fhaA
Conserved protein with FHA domain, FhaA; Regulates cell growth and peptidoglycan synthesis by binding to MviN. May inhibit the late stages of peptidoglycan synthesis.
 
 
 0.763
cpdA
Class III cyclic nucleotide phosphodiesterase (cNMP PDE); Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. Can also hydrolyze cGMP, p- nitrophenyl phosphate (pNPP), bis-(p-nitrophenyl phosphate) (bis(pNPP)), p-nitrophenyl phenylphosphonate (pNPPP) and 2',3'-cAMP. May play a role in pathogenicity, not only by hydrolyzing cAMP, but also by altering properties of the cell wall.
  
  
 0.722
mbtB
Phenyloxazoline synthase MbtB (phenyloxazoline synthetase); Involved in the initial steps of the mycobactin biosynthetic pathway. Putatively couples activated salicylic acid with serine or threonine and cyclizes this precursor to the hydroxyphenyloxazoline ring system present in this class of siderophores. Essential for growth in macrophages; Belongs to the ATP-dependent AMP-binding enzyme family. MbtB subfamily.
  
  
 0.694
qcrC
Probable ubiquinol-cytochrome C reductase QcrC (cytochrome C subunit); Cytochrome b subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of ubiquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
  
 
 0.687
Rv0516c
Possible anti-anti-sigma factor; Rv0516c, (MTCY20G10.06c), len: 158 aa. Possible anti-anti-sigma factor, showing some similarity to Rv1365c|MTCY02B10_29 from Mycobacterium tuberculosis (128 aa), FASTA scores: E(): 0.0012, (27.4% identity in 124 aa overlap).
