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:
some 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

btuFPart of the ABC transporter complex BtuCDF involved in vitamin B12 import. Binds vitamin B12 and delivers it to the periplasmic surface of BtuC (266 aa)    
Predicted Functional Partners:
btuD
Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system
  
 
 0.999
btuC
Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Involved in the translocation of the substrate across the membrane
  
 0.999
yadS
annotation not available
     
 0.974
btuB
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. Is also a receptor for bacteriophages BF23 and C1, and for A and E colicins.

mtn
Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively . Also cleaves 5'-deoxyadenosine, a toxic by-product of radical S-adenosylmethionine (SAM) enzymes, into 5- deoxyribose and adenine. Thus, is required for in vivo function of the radical SAM enzymes biotin synthase and lipoic acid synthase, that are inhibited by 5'-deoxyadenosine accumulation . Can also use 5'-isobutylthioadenosine, 5'-n-butylthioa [...]

fhuD
Part of the ABC transporter complex FhuCDB involved in iron(3+)-hydroxamate import. Binds the iron(3+)-hydroxamate complex and transfers it to the membrane-bound permease. Required for the transport of all iron(3+)-hydroxamate siderophores such as ferrichrome, gallichrome, desferrioxamine, coprogen, aerobactin, shizokinen, rhodotorulic acid and the antibiotic albomycin.

dgt
dGTPase preferentially hydrolyzes dGTP over the other canonical NTPs
     
 0.864
fhuC
Part of the ABC transporter complex FhuCDB involved in iron(3+)-hydroxamate import. Responsible for energy coupling to the transport system
 
 
 0.855
metQ
This protein is a component of a D-methionine permease, a binding protein-dependent, ATP-driven transport system.
     
 0.755
fecD
Part of the binding-protein-dependent transport system for citrate-dependent Fe(3+). Probably responsible for the translocation of the substrate across the membrane
