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

SCO1646Hypothetical protein; 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. (72 aa)    
Predicted Functional Partners:
SCO1648
AAA 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.

SCO1644
20S proteasome beta-subunit precursor; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The S.coelicolor proteasome is able to cleave oligopeptides after hydrophobic residues, but not after basic or acidic residues, thus displaying chymotrypsin-like activity but not trypsin-like activity.

SCO1643
20S proteasome alpha-subunit; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The S.coelicolor proteasome is able to cleave oligopeptides after hydrophobic residues, but not after basic or acidic residues, thus displaying chymotrypsin-like activity but not trypsin-like activity. Belongs to the peptidase T1A family.

SCO1640
Conserved hypothetical protein SCI41.23c; 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.
