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.

pupProkaryotic 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. (64 aa)    
Predicted Functional Partners:
arc
Proteasome 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 subunit beta; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1B family.
 
   
 0.978
prcA
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.

ORB38572.1
Proteasome accessory factor PafA2; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.944
pafA
Pup--protein ligase; 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.

ORB44900.1
AAA family ATPase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the AAA ATPase family.
   
 
 0.817
ORB37356.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.725
ectC
L-ectoine synthase; Catalyzes the circularization of gamma-N-acetyl-alpha,gamma- diaminobutyric acid (ADABA) to ectoine (1,4,5,6-tetrahydro-2-methyl-4- pyrimidine carboxylic acid), which is an excellent osmoprotectant.
       0.535
ORB38573.1
Ectoine hydroxylase; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.525
ORB38575.1
Diaminobutyrate--2-oxoglutarate transaminase; Catalyzes reversively the conversion of L-aspartate beta- semialdehyde (ASA) to L-2,4-diaminobutyrate (DABA) by transamination with L-glutamate; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
