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

ML1316
Probable AAA-family 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.

ML1321
Conserved hypothetical 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.
 
 
 
 0.995
ML1328
Possible DNA-binding 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.

ML1320
Conserved hypothetical protein; Highly similar to many proteins of undefined function including: Rhodococcus sp. TR:Q53081 (EMBL:U26422) (499 aa); Fasta score E(): 0, 83.5% identity in 502 aa overlap and Mycobacterium tuberculosis RV2112C TR:O33247 (EMBL:Z97559) (554 aa); Fasta score E(): 0, 95.4% identity in 504 aa overlap.
 
  
 0.961
ML0115
Conserved hypothetical protein; Interacts with the core proteasome alpha-subunit (PrcA) through its C-terminal hydrophobic-tyrosine-X motif (HbYX motif). Interaction of Bpa with the proteasome stimulates proteosomal peptidase and casein degradation activity, which suggests Bpa could play a role in the removal of non-native or damaged proteins by influencing the conformation of the proteasome complex upon interaction. Belongs to the Bpa family.

glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate; Belongs to the FGGY kinase family.
   
 0.911
panB
3-methyl-2-oxobutanoate hydroxymethyltransferase; Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is transferred onto alpha- ketoisovalerate to form ketopantoate; Belongs to the PanB family.
      
 0.713
ML0055
Conserved hypothetical protein; Part of the ESX-1 / type VII specialized secretion system (T7SS), which exports several proteins including EsxA and EsxB. EccA1 exhibits ATPase activity and may provide energy for the export of ESX-1 substrates (By similarity).
   
 0.653
ML2537
Conserved hypothetical protein; Part of an ESX-3 / type VII specialized secretion system (T7SS), which exports several proteins. EccA3 exhibits ATPase activity and may provide energy for the export of ESX-3 substrates (By similarity).
