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

arcProteasome-associated 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. (583 aa)    
Predicted Functional Partners:
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.
 
 0.999
prcB
Proteasome endopeptidase complex, beta component Threonine peptidase. MEROPS family T01B; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family.
 
 0.999
pup
Prokaryotic ubiquitin-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.
 
 
 
 0.999
SDS56080.1
Proteasome lid subunit RPN8/RPN11, contains Jab1/MPN metalloenzyme (JAMM) motif.
  
 0.993
glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate; Belongs to the FGGY kinase family.
 
 
 0.992
SDS99015.1
Proteasome accessory factor A.
  
 0.952
pafA
Proteasome accessory factor A; 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.
  
 0.951
SDS16791.1
Colicin V production protein.
  
 
 0.923
