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

speFSimilar to E. coli ornithine decarboxylase isozyme, inducible (AAC73787.1); Blastp hit to AAC73787.1 (732 aa), 91% identity in aa 1 - 732. (732 aa)    
Predicted Functional Partners:
potE
APC family, putrescine/ornithine antiporter; Catalyzes both the uptake and excretion of putrescine. The uptake of putrescine is dependent on the membrane potential and the excretion involves putrescine-ornithine antiporter activity. Belongs to the amino acid-polyamine-organocation (APC) superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2) family.
 
  
 0.999
speB
Agmatinase; Catalyzes the formation of putrescine from agmatine. Belongs to the arginase family. Agmatinase subfamily.
    
 0.988
speE
Spermidine 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.
 
 
 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.
     
 0.936
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.
   
 
 0.913
speC
Similar to E. coli ornithine decarboxylase isozyme (AAC76002.1); Blastp hit to AAC76002.1 (731 aa), 87% identity in aa 21 - 731.
  
  
0.903
STM0699
Putative cytoplasmic protein.
  
    0.900
cadB
APC family lysine/cadaverine transport protein; Similar to E. coli transport of lysine/cadaverine (AAC77093.1); Blastp hit to AAC77093.1 (444 aa), 90% identity in aa 1 - 440.
 
  
 0.833
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.
     
 0.685
yghA
Similar to E. coli putative oxidoreductase (AAC76039.1); Blastp hit to AAC76039.1 (294 aa), 93% identity in aa 1 - 294.
