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

phoRRv0758, (MTCY369.03), len: 485 aa. Possible phoR,two component system response phosphate sensor kinase membrane-associated, highly similar to various sensor kinases e.g. CAC32361.1|AL583945 putative two component system histidine kinase from Streptomyces coelicolor (524 aa); NP_349365.1|NC_003030 Membrane-associated sensory histidine kinase with HAMP domain from Clostridium acetobutylicum (482 aa); and similar to phoP proteins e.g. NP_372216.1|NC_002758 alkaline phosphatase synthesis sensor protein from Staphylococcus aureus (554 aa); P23545|PHOR_BACSU alkaline phosphatase synthesis se [...] (485 aa)

phoP
Rv0757, (MTCY369.02), len: 247 aa. Possible phoP,two component system response phosphate regulon transcriptional regulator (see citations below), highly similar to various transcriptional regulators e.g. CAC32360.1|AL583945 putative two component system response regulator from Streptomyces coelicolor (271 aa); T45446 probable two-component response regulator from Mycobacterium leprae (253 aa); and similar to phoP proteins e.g. P13792|PHOP_BACSU alkaline phosphatase synthesis transcription regulatory protein from Bacillus subtilis (240 aa), FASTA scores: opt: 594, E(): 2.3e-33, (41.0% i [...]

regX3
Sensory transduction protein RegX3; Probably forms part of a two-component regulatory system RegX3/SenX3.

trcR
Rv1033c, (MTCY10G2.16), len: 257 aa. TrcR,two-component regulatory protein (see citations below),similar to Q50825 two component response regulator from Mycobacterium tuberculosis (234 aa), FASTA scores: opt: 628, E(): 0, (46.0% identity in 226 aa overlap). Note that in vitro autophosphorylation of TrcS requires the presence of Mn2+or Ca2+as a divalent cation cofactor and subsequent transphosphorylation of TrcR is evident in the presence of TrcS-phosphate and Ca2+.

tcrX
Probable two component transcriptional regulatory protein TcrX; Member of the two-component regulatory system TcrY/TcrX.
 
 0.880
tcrA
Two component DNA binding transcriptional regulatory protein TcrA; Member of the three-protein two-component system HK1/HK2/TcrA.
 
 0.877
mtrA
Two component sensory transduction transcriptional regulatory protein MtrA; Member of the two-component regulatory system MtrA/MtrB. Binds direct repeat motifs of sequence 5'-GTCACAGCG-3', phosphorylation confers higher affinity. Overexpression decreases bacteria viability upon infection of human THP-1 macrophage cell line, due at least in part to impaired blockage of phagosome-lysosome fusion (upon infection bacteria usually remain in phagosomes). Infecting C57BL/6 mice with an overexpressing strain leads to an attentuated infection in both spleen and lungs. The level of dnaA mRNA inc [...]
 
 0.866
prrA
Two component response transcriptional regulatory protein PrrA; 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. Upon phosphorylation by PrrB, functions as a transcription regulator by direct binding to promoter regions of target genes to positively regulate their expression. Autoregulates its own expression.

Rv3454
Rv3454, (MTCY13E12.07), len: 422 aa. Probable conserved integral membrane protein, showing some similarity to various proteins (generally transporters) e.g. Q9I5C8|PA0811 probable MFS transporter from Pseudomonas aeruginosa (415 aa), FASTA scores: opt: 145,E(): 0.13, (28.2% identity in 188 aa overlap); Q01266|YHYC_PSESN hypothetical protein in HYUC 3'region (ORF 5) (fragment) from Pseudomonas sp. strain NS671 (245 aa), FASTA scores: opt: 130, E(): 0.75, (24.65% identity in 134 aa overlap); Q9I242|PA2073 probable transporter (membrane subunit) from Pseudomonas aeruginosa (476 aa),FASTA [...]

mprA
Response regulator MprA; 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. Functions as a transcriptional regulator that recognizes a 19-bp nucleotide motif comprizing two loosely conserved 8-bp direct DNA-binding motif repeats separated by a 3-bp spacer region. MprB/MprA is involved in regulation of numerous stress-responsive genes, including up-regulation of two sigma factors, sigE and sigB as well [...]
