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 (psmB); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin- like activity. (224 aa)    
Predicted Functional Partners:
psmA
Proteasome, subunit alpha (psmA); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin- like activity.

Proteasome regulatory AAA-ATPase; 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 ATPase-20 [...]
