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
ctpVProbable metal cation transporter P-type ATPase CtpV; Necessary for copper homeostasis and likely functions as a copper exporter. Also required for full virulence. (770 aa)    
Predicted Functional Partners:
Rv0968
Conserved protein; Rv0968, (MTCY10D7.06c), len: 98 aa. Conserved protein, part of cso operon, similar to NP_301579.1|NC_002677 conserved hypothetical protein from Mycobacterium leprae (92 aa). Also highly similar to conserved hypothetical proteins from Mycobacterium tuberculosis e.g. Rv3269 (93 aa), FASTA score: (51.1% identity in 94 aa overlap); and Rv1993c (90 aa).
  
  
 0.985
Rv0970
Rv0970, (MTCY10D7.04c), len: 210 aa. Probable conserved integral membrane protein, part of cso operon,equivalent to NP_302348.1|NC_002677 probable integral membrane protein from Mycobacterium leprae (210 aa).
  
  
 0.961
csoR
Copper-sensitive operon repressor CsoR; Copper-sensitive repressor that has a key role in copper homeostasis. It is part of the cso operon involved in the cellular response to increasing concentrations of copper inside the bacterium, which can be highly toxic. In the presence of copper, CsoR fully dissociates from the promoter in the cso operon, leading to the transcription of its genes. Binds to a GC-rich pseudopallindromic sequence, 5'-GTAGCCCACCCCCAGTGGGGTGGGA-3', in the cso promoter region.
 
  
 0.936
mmcO
Probable oxidase; Required for copper resistance. In vitro, oxidizes organic substrates and Fe(2+). May act in vivo by oxidation of toxic periplasmic Cu(+); Belongs to the multicopper oxidase family.
 
  
 0.729
ricR
Conserved protein; Under low copper conditions, represses the expression of lpqS, Rv2963, mymT, socA, socB, mmcO and its own expression. In the presence of copper, RicR dissociates from DNA, leading to the expression of the target genes. Members of the RicR regulon are important for copper resistance during infections and full virulence in a mouse model of infection.
  
  
 0.656
mymT
Metallothionein, MymT; Metallothioneins are small proteins that have a high content of cysteine residues wich allow them to bind heavy metal ions through clusters of thiolate bonds. MymT binds up to seven ions of Cu(+), with a preference for four to six Cu(+) ions, in a solvent-shielded core. MymT protects M.tuberculosis from copper toxicity.
      
 0.655
sodC
Periplasmic superoxide dismutase [Cu-Zn] SodC; Destroys radicals which are normally produced within the cells and which are toxic to biological systems. May play a role in favoring mycobacterial survival in phagocytes (By similarity).
    
 0.649
ctpI
Rv0107c, (MTCY251.26c, MTV031.01c), len: 1632 aa. Probable ctpI, cation-transporting ATPase I P-type, highly similar to NP_302704.1|NC_002677 probable cation transport ATPase from Mycobacterium leprae (1609 aa); and similar to others e.g. CAB69720.1|AL137166 putative transport ATPase from Streptomyces coelicolor (1472 aa); ATA1_SYNY|P37367 cation-transporting ATPase pma1 from Synechocystis sp. (915 aa), FASTA scores: opt: 603, E(): 6.6e-29, (32.4% identity in 710 aa overlap); etc. Also similar to MTCY39.21c and MTCY22G10.22c from Mycobacterium tuberculosis, FASTA score: (34.4% identity [...]

ctpH
Rv0425c, (MTCY22G10.22c), len: 1539 aa. Possible ctpH, metal cation-transporting P-type ATPase (transmembrane protein), showing some similarity with CAA17934.1|AL022118|13093871|CAC32203.1|AL583926 putative cation-transporting ATPase from Mycobacterium leprae (1609 aa). Also similar to others ATPases e.g. AE000873_1 cation-transporting P-ATPase from Methanobacterium thermoautotrop (844 aa), FASTA score: (30.5% identity in 827 aa overlap); AB69720.1|AL137166 putative transport ATPase from Streptomyces coelicolor (1472 aa); etc. C-terminal region similar to other ATPases from Mycobacteri [...]
