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

prcA20S proteasome, A and B subunits; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1A family. (234 aa)    
Predicted Functional Partners:
arc
Vesicle-fusing 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.

prcB
Proteasome endopeptidase complex, beta component; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family.

Acel_2102
KEGG: tfu:Tfu_0071 hypothetical protein.
  
 
 
 0.991
pafA
Protein of unknown function DUF245 domain protein; 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.
  
 0.977
pup
Protein of unknown function DUF797; Protein modifier that is covalently attached to lysine residues of substrate proteins, thereby targeting them for proteasomal degradation. The tagging system is termed pupylation. Belongs to the prokaryotic ubiquitin-like protein family.

Acel_1689
PFAM: Mov34/MPN/PAD-1 family protein; KEGG: tfu:Tfu_2370 Mov34/MPN/PAD-1.
   
 0.941
dop
Protein of unknown function DUF245 domain protein; Displays depupylase (DPUP) activity, removing conjugated Pup from target proteins; is thus involved in the recycling of Pup and may function similarly to deubiquitinases (DUBs) in eukaryotes to prevent or promote proteasomal degradation of certain proteins. Is also able to catalyze the deamidation of the C-terminal glutamine to glutamate in a variant of the prokaryotic ubiquitin-like protein Pup; however, since Pup from A.cellulolyticus possesses a C-terminal glutamate, this deamidase activity may be of no significance in vivo.
  
 0.895
Acel_1680
Chaperonin Cpn10; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family.
  
    0.620
Acel_1200
KEGG: tfu:Tfu_1771 similar to transcriptional regulator.
 
   
 0.467
alaS
alanyl-tRNA synthetase; Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.
