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

parD1Possible antitoxin ParD1; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli neutralizes the effect of cognate toxin ParE1. (83 aa)    
Predicted Functional Partners:
parE1
Possible toxin ParE1; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli inhibits cell growth and colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin ParD1.

parD2
Possible antitoxin ParD2; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli neutralizes the effect of cognate toxin ParE2.
      
 0.868
vapC30
Possible toxin VapC30. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB30.; Belongs to the PINc/VapC protein family.

cobB-2
Transcriptional regulatory protein; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form (By similarity). Reactivates acetylated acetyl-CoA synthetase (ACS) through an NAD-dependent deacetylation. Is able to ADP-ribosylate itself.

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.
