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

pupUbiquitin-like protein Pup; Protein modifier that is covalently attached to lysine residues of substrate proteins, thereby targeting them for proteasomal degradation. The tagging system is termed pupylation. (67 aa)    
Predicted Functional Partners:
arc
Proteasome ATPase; ATPase which is responsible for recognizing, binding, unfolding and translocation of pupylated proteins into the bacterial 20S proteasome core particle. May be essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C-termini of the proteasomal ATPase may function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis.
 
 
 
 0.999
prcB
Proteasome, beta subunit; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family.
 
 
 
 0.978
prcA
Proteasome, alpha subunit; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1A family.
 
 
 
 0.973
pafA
Proteasome accessory factor PafA; Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side- chain amino group of a substrate lysine.

Proteasome accessory factor PafA2.
 
  
 0.864
B005_1889
Hypothetical protein.
  
   
 0.749
B005_2822
Polyketide cyclase / dehydrase and lipid transport family protein.
  
     0.543
mshD
Mycothiol synthase; Catalyzes the transfer of acetyl from acetyl-CoA to desacetylmycothiol (Cys-GlcN-Ins) to form mycothiol.
  
     0.540
whiB-3
Transcription factor WhiB family protein; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
  
     0.497
mca
Mycothiol conjugate amidase Mca; A mycothiol (MSH, N-acetylcysteinyl-glucosaminyl-inositol) S- conjugate amidase, it recycles conjugated MSH to the N-acetyl cysteine conjugate (AcCys S-conjugate, a mercapturic acid) and the MSH precursor. Involved in MSH-dependent detoxification of a number of alkylating agents and antibiotics; Belongs to the MshB deacetylase family. Mca subfamily.
