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

mbcAProbable transcriptional regulatory protein; Antitoxin component of a type II toxin-antitoxin (TA) system. Neutralizes the activity of cognate toxin MbcT by blocking access to the toxin active site. (113 aa)    
Predicted Functional Partners:
mbcT
Hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. Neutralized by cognate antitoxin MbcA. Degrades NAD(+) by phosphorolysis. Expression in the absence of its cognate antitoxin MbcA causes dramatic reduction of intracellular NAD(+) levels and is deleterious to cell growth, causing cell death. In a SCID mouse infection model, mice infected with bacteria overexpressing this protein survive longer. Overexpression of this protein in a mouse infection model at 21 days leads to bacterial death, and shows a synergistic 100-fold increase in mouse survival when combi [...]

Rv0023
Rv0023, (MTCY10H4.23), len: 256 aa. Possible transcriptional regulator. Contains probable helix-turn helix motif from aa 19 to 40 (Score 1615, +4.69 SD).
   
  
 0.861
Rv0238
Rv0238, (MTV034.04), len: 204 aa. Possible transcriptional regulatory protein, TetR family, equivalent to AL022486|MLCB1883_9|T44874 probable transcription regulator from Mycobacterium leprae (208 aa), FASTA scores: opt: 1029, E(): 0, (80.9% identity in 199 aa overlap). Also similar to others e.g. CAB77290.1|AL160312 putative TetR-family regulatory protein from Streptomyces coelicolor (240 aa). Also similar to Mycobacterium tuberculosis proteins Z95120|Rv3208 (228 aa), FASTA scores: opt: 266,E(): 8.3e-12, (28.1% identity in 196 aa overlap); and Rv1019 (197 aa).

Rv2034
ArsR repressor protein; Involved in the regulation of lipid metabolism and hypoxic response. Positively regulates transcription of various genes, such as phoP, groEL2 and dosR. Negatively regulates its own transcription. Acts by binding to a specific palindromic sequence motif in promoter regions.
   
  
 0.644
higA2
Transcriptional regulatory protein; Putative antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin would be HigB2.
   
  
 0.533
mftR
Probable transcriptional regulatory protein; May regulate a gene cluster involved in mycofactocin expression. Mycofactocin is a conserved polypeptide that might serve as an electron carrier.

vapB23
Possible antitoxin VapB23; Putative antitoxin component of a possible type II toxin- antitoxin (TA) system. The cognate toxin is VapC23.

Rv1990A
Rv1990A, len: 111 aa. Possible dehydrogenase (fragment), similar to N-terminal part of several dehydrogenases and hypothetical proteins, e.g. Rv2750|MTV002.15|AL008967 from Mycobacterium tuberculosis (272 aa), FASTA scores: opt: 151, E(): 0.0045, (47.45% identity in 78 aa overlap), but lacks C-terminal part. Maybe a pseudogene. Also similar to U17129|RSU17129_7 putative short-chain alcohol dehydrogenase from Rhodococcus erythropolis (275 aa), FASTA scores: opt: 142, E(): 0.018,(54.15% identity in 48 aa overlap). This region is a possible MT-complex-specific genomic island (See Becq et [...]
