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

btuBVitamin B12/cobalamin outer membrane transporter; Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans- periplasmic membrane protein TonB; Belongs to the TonB-dependent receptor family. BtuB (TC 1.B.14.3.1) subfamily. (622 aa)    
Predicted Functional Partners:
dga
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
 
  
 0.925
tonB
Energy transducer TonB; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Belongs to the TonB family.

AKA39962.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 
 
 0.883
ompF
Porin; Allows for ions and hydrophilic solutes to cross the outer membrane; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the Gram-negative porin family.
    
 0.855
AKA38813.1
Cell division protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 
 0.836
ompA1
Membrane protein; OmpA is believed to be a porin, involved in diffusion of nonspecific small solutes across the outer membrane. It is the most abundant integral protein of the outer membrane of E. coli, and it is known to play a role as a phage receptor, a mediator of F-factor dependent conjugation, and in maintaining the structural shape of the outer membrane; 3a; II*; G; d; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
  
  
 0.764
meoA
Membrane protein; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the Gram-negative porin family.
    
 0.720
lamB
Maltoporin; Involved in the transport of maltose and maltodextrins. Belongs to the porin LamB (TC 1.B.3) family.
     
 0.679
metH
B12-dependent methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
 
   
 0.672
tolB
Translocation protein TolB; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane.
