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

speESpermidine synthase; Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. (287 aa)    
Predicted Functional Partners:
speH
Adenosylmethionine decarboxylase proenzyme; Catalyzes the decarboxylation of S-adenosylmethionine to S- adenosylmethioninamine (dcAdoMet), the propylamine donor required for the synthesis of the polyamines spermine and spermidine from the diamine putrescine; Belongs to the prokaryotic AdoMetDC family. Type 1 subfamily.
 
 0.999
SDC36700.1
Ornithine decarboxylase; Belongs to the Orn/Lys/Arg decarboxylase class-II family.
  
 0.953
SDC01777.1
5-methylthioadenosine/S-adenosylhomocysteine deaminase.
   
  0.942
SDC63291.1
Cupin domain-containing protein.
       0.791
fliM
Flagellar motor switch protein FliM.
    
   0.748
metK
Methionine adenosyltransferase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
 
 0.618
nadE
NAD+ synthase (glutamine-hydrolysing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
 
 0.561
lysA
Diaminopimelate decarboxylase.
  
 0.524
SDC60153.1
Acetylornithine/succinyldiaminopimelate/putresci ne aminotransferase; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
     
 0.514
SDC08602.1
Predicted amidohydrolase.
  
 
 0.502
