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

CAZ96800.1TonB-like protein; TonB is an energy-transducer for TonB-dependent receptors of Gram-negative bacteria. Energy flows from the cytoplasmic membrane into the outer membrane via a complex consisting of TonB, ExbB and ExbD proteins which are anchored in the cytoplasmic membrane. TonB interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates; Although belonging to the TonB family, this protein seems to contain a signal peptide cleaved between the residues 17 and 18, which is unsual for c [...] (212 aa)    
Predicted Functional Partners:
CAZ97258.1
TonB-dependent Receptor; Protein localized in the outer membrane involved in uptake of macromolecules that are too large to diffuse via the outer membrane porins channels or are encountered at very low concentrations; Contains a carboxypeptidase regulatory domain (34-108) and the Plug module (124-231) acting as a channel gate; The signal peptide is cleaved between the residues 30 and 31; Family membership.

exbD2
ExbD is involved in the tonB-dependent energy-dependent transport of various receptor-bound substrates. ExbD forms a complex with ExbB. This complex is required for the efficient energization of tonB from the protomotive force; Contains a N-terminal transmembrane helix; Belongs to the exbD/tolR family; Localized in the cytoplasmic membrane; High confidence in function and specificity.
 
 
 0.749
exbD1
ExbD is involved in the tonB-dependent energy-dependent transport of various receptor-bound substrates. ExbD forms a complex with ExbB. This complex is required for the efficient energization of tonB from the protomotive force; Contains a N-terminal transmembrane helix; Belongs to the exbD/tolR family; Localized in the cytoplasmic membrane; High confidence in function and specificity.
 
 
 0.748
tolR
TolR, involved in the tonB-independent uptake of biopolymers, forms a complex with the proteins TolQ. This complex energizes TolA from the potential energy of the ion electrochemical gradient. TolA energized, interacts with the outer membrane protein Pal (OprL). The Tol-Pal complex is required for maintaining outer membrane integrity, the transport (uptake) filamentous DNA and is the conduct for bacteriophages; Contains a N-terminal transmembrane helix; Belongs to the exbD/tolR family; Localized in the cytoplasmic membrane; High confidence in function and specificity.
 
 
 0.689
CAZ96814.1
Beta-helix fold protein; This protein likely adopts a right handed parallel beta-helix fold. Displays also a C-terminal PKD domain; Signal peptide cleaved between the residues 28 and 29; Localized in the periplasmic space; Function unclear.
  
     0.667
exbB
ExbB is involved in the tonB-dependent energy-dependent transport of various receptor-bound substrates. ExbB protects ExbD from proteolytic degradation and functionally stabilizes tonB. TonB is coupled to the protomotive force by the ExbB/ExbD complex which is required for the energization of TonB; Contains four transmembrane segments; Belongs to the ExbB/TolQ family; Signal peptide cleaved between residues 23 and 24; Localized in the cytoplasmic membrane; High confidence in function and specificity.
 
 
 0.657
CAZ97203.1
TonB-dependent Transducer; Protein localized in the outer membrane involved in uptake of macromolecules that are too large to diffuse via the outer membrane porins; The presence of an additional N-terminal extension (Secretin/TonB (STN) domain (50-101)) that probably interacts with an anti-sigma factor, would be responsible of the signal transduction; Contains a carboxypeptidase regulatory domain (106-180) and a Plug module (197-327) acting as the channel gate; The signal peptide is cleaved between the residue 22 and 23; Family membership.
 
 
 0.633
CAZ96815.1
Modular protein containing a N-terminal domain adopting a parallel beta-helix fold and a C-terminal carbohydrate binding module of the family 13 (CBM13). The N-terminal domain is distantly related to the polysaccharide lyases of the family 9 (PL9). Features a signal peptide cleaved between residues 26 and 27. Localized in the periplasm; Specificity unclear.

CAZ97359.1
TonB-dependent Receptor; Protein localized in the outer membrane involved in uptake of macromolecules that are too large to diffuse via the outer membrane porins channels or are encountered at very low concentrations; Contains a carboxypeptidase regulatory domain (22-108) and the Plug module (122-217) acting as a channel gate; The signal peptide is putatively cleaved between the residues 25 and 26; Family membership.
