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

bltDSpermine/spermidine acetyltransferase; Acetylates both spermidine and spermine at primary propyl amine moieties, with spermine being the preferred substrate. (152 aa)    
Predicted Functional Partners:
bltR
Transcriptional regulator; Activates transcription of the blt gene in response to structurally dissimilar drugs.
 
  
 0.974
blt
Efflux transporter; Energy-dependent efflux pump responsible for decreased drug accumulation in multi-drug-resistant cells. Probably uses a transmembrane proton gradient as the energy source. Causes the efflux of a variety of toxic substances, including such structurally diverse compounds as ethidium bromide, rhodamine and acridine dyes, tetraphenylphosphonium, puromycin, chloramphenicol, doxorubicin, and fluoroquinolone antibiotics; Belongs to the major facilitator superfamily. TCR/Tet family.
  
  
 0.946
speE
Spermidine synthase; Involved in the cell growth and proliferation. Catalyzes the irreversible transfer of a propylamine group from the amino donor S- adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4- diaminobutane) to yield spermidine (Probable). Belongs to the spermidine/spermine synthase family.
    
 0.901
speB
Agmatinase; Catalyzes the formation of putrescine from agmatine; Belongs to the arginase family. Agmatinase subfamily.
     
  0.900
feuC
Iron-uptake protein; Involved in the uptake of iron. Probably responsible for the translocation of the substrate across the membrane.
      
 0.888
ydjO
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      
 0.848
prmC
Glutamine methylase of release factor 1 (and perhaps others) at a GGQ site; Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif; Belongs to the protein N5-glutamine methyltransferase family. PrmC subfamily.
  
  
 0.727
yusV
iron(III)-siderophore transporter (ATP binding component); Provides the ATPase subunit for at least 2 ABC transporter complexes; YfiYZ/YfhA/YusV involved in import of the iron-hydroxamate siderophores schizokinen, arthrobactin and corprogen (Probable), and FeuABC/YusV involved in import of the catecholate siderophores bacillibactin and enterobactin (Probable). Probably responsible for energy coupling to the transport system (By similarity).
      
 0.607
yraL
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
     0.578
feuA
Iron hydroxamate-binding lipoprotein; Involved in the uptake of iron. Belongs to the bacterial solute-binding protein 8 family.
      
 0.577
