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

psmBProteasome, subunit beta; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family. (219 aa)    
Predicted Functional Partners:
psmA
Proteasome, subunit alpha; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1A family.
 
0.999
psmR
Proteasome-activating nucleotidase (PAN); ATPase which is responsible for recognizing, binding, unfolding and translocation of substrate proteins into the archaeal 20S proteasome core particle. Is 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 function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Unfolding activity requires energy from ATP hydrolysis, whereas ATP binding alone promotes A [...]

rpl40e
LSU ribosomal protein L40E; Belongs to the eukaryotic ribosomal protein eL40 family.
   
 0.946
MMP0176
CDC48 cell division cycle protein family member; ATP/GTP-binding site motif A (P-loop); Citation: Mol. Gen. Genet. (1999) 262: 559-567, Cell (1995) 82: 885-893.
   
 0.938
mtrA
N5-methyltetrahydromethanopterin: methyltransferase, subunit A; Part of a complex that catalyzes the formation of methyl- coenzyme M and tetrahydromethanopterin from coenzyme M and methyl- tetrahydromethanopterin. This is an energy-conserving, sodium-ion translocating step; Belongs to the MtrA family.
   
  
 0.873
MMP0694
Beta-lactamase-like:KH domain.
  
  
 0.819
leuS
Leucyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 
 0.770
MMP0914
Conserved hypothetical archaeal protein.
 
 
 0.709
aEF-1-2
Translation elongation factor aEF-1 beta; Promotes the exchange of GDP for GTP in EF-1-alpha/GDP, thus allowing the regeneration of EF-1-alpha/GTP that could then be used to form the ternary complex EF-1-alpha/GTP/AAtRNA.
   
 
 0.676
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.
