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 (speE); Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. (269 aa)    
Predicted Functional Partners:
speH
Conserved hypothetical protein; 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.

AF_0646
Agmatinase (speB); Similar to GB:M32363 SP:P16936 PID:147859 PID:551839 PID:882466 percent identity: 33.33; identified by sequence similarity; putative; Belongs to the arginase family.
 
 
 0.981
AF_1788
Methylthioadenosine phosphorylase (mtaP); Purine nucleoside phosphorylase which is highly specific for 6-oxopurine nucleosides. Cleaves guanosine or inosine to respective bases and sugar-1-phosphate molecules. Involved in purine salvage.
 
 
 0.954
mtaD1
N-ethylammeline chlorohydrolase (trzA-1); Catalyzes the deamination of 5-methylthioadenosine and S- adenosyl-L-homocysteine into 5-methylthioinosine and S-inosyl-L- homocysteine, respectively. Is also able to deaminate adenosine. Belongs to the metallo-dependent hydrolases superfamily. MTA/SAH deaminase family.
  
  0.917
mtaD2
N-ethylammeline chlorohydrolase (trzA-2); Catalyzes the deamination of 5-methylthioadenosine and S- adenosyl-L-homocysteine into 5-methylthioinosine and S-inosyl-L- homocysteine, respectively. Is also able to deaminate adenosine. Belongs to the metallo-dependent hydrolases superfamily. MTA/SAH deaminase family.

AF_2333
Conserved hypothetical protein; Similar to GB:L77117 PID:1591952 percent identity: 45.50; identified by sequence similarity; putative.
       0.773
lysA
Diaminopimelate decarboxylase (lysA); Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine.
  
 
 0.699
pyrG
CTP synthase (pyrG); Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
    0.648
AF_0115
Conserved hypothetical protein; Similar to GB:X52543 PID:46506 SP:P55177 percent identity: 31.85; identified by sequence similarity; putative.
 
  
 0.636
trpCD
Anthranilate synthase component II (trpD); Bifunctional enzyme that catalyzes the second and fourth steps of tryptophan biosynthetic pathway. The second step is catalyzed by the anthranilate phosphoribosyltransferase, coded by the TrpD domain and the fourth step is catalyzed by indole-3-glycerol phosphate synthase, coded by the TrpC domain (By similarity).
