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. (286 aa)    
Predicted Functional Partners:
speD
S-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 2 subfamily.
 
 
 0.999
speB
Agmatinase; Catalyzes the formation of putrescine from agmatine. Belongs to the arginase family. Agmatinase subfamily.
  
 
 0.989
speC
Similar to E. coli ornithine decarboxylase isozyme (AAC76002.1); Blastp hit to AAC76002.1 (731 aa), 87% identity in aa 21 - 731.
  
 
 0.978
speF
Similar to E. coli ornithine decarboxylase isozyme, inducible (AAC73787.1); Blastp hit to AAC73787.1 (732 aa), 91% identity in aa 1 - 732.
 
 
 0.974
speG
Similar to E. coli spermidine N1-acetyltransferase (AAC74656.1); Blastp hit to AAC74656.1 (186 aa), 91% identity in aa 1 - 186.
    
 0.944
oat
Putative acetylornithine aminotransferase; Catalyzes the aminotransferase reaction from putrescine to 2- oxoglutarate, leading to glutamate and 4-aminobutanal, which spontaneously cyclizes to form 1-pyrroline. This is the first step in one of two pathways for putrescine degradation, where putrescine is converted into 4-aminobutanoate (gamma-aminobutyrate or GABA) via 4- aminobutanal. Also functions as a cadaverine transaminase in a a L- lysine degradation pathway to succinate that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate.
  
  
 0.930
adi
Arginine decarboxylase; Catabolic; inducible by acid; similar to E. coli biodegradative arginine decarboxylase (AAC77078.1); Blastp hit to AAC77078.1 (756 aa), 92% identity in aa 1 - 756.
  
  
 0.909
gsp
Bifunctional; similar to E. coli glutathionylspermidine synthetase/amidase (AAC76024.1); Blastp hit to AAC76024.1 (619 aa), 90% identity in aa 1 - 618; glutathionylspermidine amidase.
    
  0.903
pfs
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. 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 accumulatio [...]

yadE
Putative xylanase/chitin deacetylase; Similar to E. coli orf, hypothetical protein (AAC73241.1); Blastp hit to AAC73241.1 (409 aa), 81% identity in aa 1 - 409.
