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

Mycosin-4; Rv3449, (MTCY13E12.02), len: 455 aa. Probable mycP4,membrane-anchored serine protease (mycosin) (see citation below), similar to hypothetical unknowns or proteases from Mycobacterium tuberculosis strains H37Rv and CDC1551 e.g. AAK48366|MT3998 subtilase family protein from Mycobacterium tuberculosis strain CDC1551 (411 aa), FASTA scores: opt: 747, E(): 3.5e-33, (45.65% identity in 416 aa overlap); O05461|Rv3883c|MTCY15F10.29 membrane-anchored mycosin MYCP1 (446 aa), FASTA scores: opt: 747, E(): 3.8e-33, (45.45% identity in 451 aa overlap); O53695|Rv0291|MTV035.19 probable mem [...]

grpE
Probable GrpE protein (HSP-70 cofactor); Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Severa [...]

dnaJ1
Probable chaperone protein DnaJ1; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions betwe [...]

esxT
Putative ESAT-6 like protein EsxT; Induces apoptosis of host cells via activation of NF-kappa-B.
 
  
 0.891
cpnT
Hypothetical alanine and proline rich protein; Has a dual function in uptake of nutrients and induction of host cell death. The N-terminal domain (NTD) forms an outer membrane channel and is used for uptake of nutrients across the outer membrane. The secreted C-terminal toxic domain (TNT) acts as a glycohydrolase, which hydrolyzes the essential cellular coenzyme NAD(+) in the cytosol of infected macrophages, leading to necrotic host cell death. Both functions are required for survival, replication and cytotoxicity of M.tuberculosis in macrophages.

esxU
Rv3445c, (MTCY77.17c), len: 105 aa. EsxU, ESAT-6 like protein (see citations below), showing weak similarity to O30373|VCD|PA2257 pyoverdine biosynthesis protein from Pseudomonas aeruginosa (215 aa), FASTA scores: opt: 103,E(): 5.6, (32.35% identity in 133 aa overlap). Seems to belong to the ESAT6 family. Start changed since first submission (-20 aa); Belongs to the WXG100 family. CFP-10 subfamily.
