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

Rv0158Probable transcriptional regulatory protein (possibly TetR-family); Rv0158, (MTV032.01), len: 214 aa. Probable transcriptional regulator, possibly TetR family, showing weak similarity to various transcriptional activators and repressors e.g. P32398|YIXD_BACSU|YHGD hypothetical transcriptional regulatory protein from Bacillus subtilis (191 aa), FASTA scores: opt:172, E(): 2.4e-05, (23.0% identity in 191 aa overlap). Contains helix-turn-helix motif at aa 32-53 (Score 1296, +3.60 SD). Could belong to the TetR/AcrR family of transcriptional regulators. (214 aa)    
Predicted Functional Partners:
ethR
Transcriptional regulatory repressor protein (TetR-family) EthR; Involved in the repression of the monooxygenase EthA which is responsible of the formation of the active metabolite of ethionamide (ETH).

kstR2
Transcriptional regulatory protein (probably TetR-family); Controls the expression of a small regulon that may play a role in the utilization of cholesterol.

Rv3488
Conserved hypothetical protein; May have transcription regulation and metal-detoxifying functions through which it may enhance intracellular survival of mycobacteria. Binds to its own promoter region and to the Rv1999c promoter region. It displays strong affinity for cadmium ions, but can also bind zinc, manganese and nickel. Expression increases the intracellular survival of recombinant M. smegmatis in murine macrophage cell line and increases its tolerance to cadmium ions.

Rv0339c
Rv0339c, (MTCY279.06c), len: 832 aa. Possible transcriptional regulator, showing very weak similarity with parts of others. Contains PS00017 ATP/GTP-binding site motif A (P-loop); and probable helix-turn helix motif from aa 778-799 (Score 1041, +2.73 SD).

lysG
Probable transcriptional regulatory protein (probably LysR-family); Positively regulates the expression of the exporter LysE and represses its own expression. Activity requires the presence of a coinducer, lysine or histidine. Acts by binding to lysG-lysE promoter region. Also up-regulates the expression of ppsB, ppsC and ppsD, by binding to the upstream region of ppsB.
