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

ahpCAlkyl hydroperoxide reductase C protein AhpC (alkyl hydroperoxidase C); Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. Together with AhpD, DlaT and Lpd, constitutes an NADH-dependent peroxidase active against hydrogen and alkyl peroxides as well as serving as a peroxynitrite reductase, thus protecting the bacterium against reactive nitrogen intermediates and oxidative stress generated by the host immune system. D [...] (195 aa)    
Predicted Functional Partners:
ahpD
Alkyl hydroperoxide reductase D protein AhpD (alkyl hydroperoxidase D); Antioxidant protein with alkyl hydroperoxidase activity. Required for the reduction of the AhpC active site cysteine residues and for the regeneration of the AhpC enzyme activity.

katG
Catalase-peroxidase-peroxynitritase T KatG; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity, oxidizing various electron donors including NADP(H). Protects M.tuberculosis against toxic reactive oxygen species (ROS) including hydrogen peroxide as well as organic peroxides and thus contributes to its survival within host macrophages by countering the phagocyte oxidative burst. Also displays efficient peroxynitritase activity, which may help the bacterium to persist in macrophages. Catalyzes the oxidative activation of the antitubercular pro- drug isoniazid (I [...]

rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.967
inhA
NADH-dependent enoyl-[acyl-carrier-protein] reductase InhA (NADH-dependent enoyl-ACP reductase); Enoyl-ACP reductase of the type II fatty acid syntase (FAS- II) system, which is involved in the biosynthesis of mycolic acids, a major component of mycobacterial cell walls. Catalyzes the NADH-dependent reduction of the double bond of 2-trans- enoyl-[acyl-carrier protein], an essential step in the fatty acid elongation cycle of the FAS-II pathway. Shows preference for long-chain fatty acyl thioester substrates (>C16), and can also use 2-trans-enoyl-CoAs as alternative substrates. The mycob [...]
