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.

bltDSpermine/spermidine acetyltransferase; Acetylates both spermidine and spermine at primary propyl amine moieties, with spermine being the preferred substrate. (152 aa)    
Predicted Functional Partners:
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.

paiA
Polyamine N-acetyltransferase; Involved in the protection against polyamine toxicity by regulating their concentration. Also could be involved in the negative control of sporulation as well as production of degradative enzymes such as alpha-amylase, levansucrase and alkaline phosphatase. Catalyzes the transfer of an acetyl group from acetyl coenzyme A (AcCoA) to an acceptor substrate and releases both CoA and the acetylated product. It possesses N1-acetyltransferase activity toward polyamine substrates including spermidine, spermine, aminopropylcadaverine, norspermidine, homospermidine [...]

speB
Agmatinase; Catalyzes the formation of putrescine from agmatine; Belongs to the arginase family. Agmatinase subfamily.
     
  0.900
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.

ydjO
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      
 0.807
feuC
Iron-uptake protein; Involved in the uptake of iron. Probably responsible for the translocation of the substrate across the membrane.
      
 0.714
bltR
Transcriptional regulator; Activates transcription of the blt gene in response to structurally dissimilar drugs.
 
    0.698
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.
  
  
 0.647
yraL
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.580
feuB
Iron-uptake protein; Involved in the uptake of iron. Probably responsible for the translocation of the substrate across the membrane.
