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; Belongs to the spermidine/spermine synthase family. (284 aa)    
Predicted Functional Partners:
speD
S-adenosylmethionine decarboxylase proenzyme precursor; 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 2 subfamily.
 
 
 0.999
speA_2
Arginine decarboxylase.
 
 0.987
nspC
Carboxynorspermidine/carboxyspermidine decarboxylase.
  
 0.973
mtnN
5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase; 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. Belongs to the PNP/UDP phosphorylase family. MtnN subfamily.
    
 0.959
AQR94968.1
N-carbamoyl-D-amino acid hydrolase.
  
 
 0.951
patA_3
Putrescine aminotransferase; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
     
 0.912
speG
Spermidine N(1)-acetyltransferase.
  
 
 0.907
speA_1
Arginine decarboxylase.
 
 0.806
punA
Purine nucleoside phosphorylase 1; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
  
 
 0.693
metK
S-adenosylmethionine synthase; 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.
