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

speBAgmatinase (speB); Catalyzes the formation of putrescine from agmatine. (284 aa)    
Predicted Functional Partners:
speE
Spermidine 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.

 0.760
leuS
leucyl-tRNA synthetase (leuS); Similar to SP:P26637 PID:1370340 PID:1403549 PID:3508 percent identity: 35.17; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.

eif5a
Translation initiation factor aIF-5A; Functions by promoting the formation of the first peptide bond; Belongs to the eIF-5A family.
  
  
 0.745
MJ_1411
Glyceraldehyde-3-phosphate dehydrogenase, NADP-dependent (gapN); Involved in F420 biosynthesis through the oxidation of lactaldehyde to lactate. The substrate preference order is propionaldehyde > DL-lactaldehyde, DL-glyceraldehyde > crotonaldehyde > glycolaldehyde > acetaldehyde, acrolein > formaldehyde. No activity was observed towards methylglyoxal or glyceraldehyde-3-phosphate. Has a preference for NAD over NADP.
  
 
 0.708
dys
Deoxyhypusine synthase (dys1); Catalyzes the NAD-dependent oxidative cleavage of spermidine and the subsequent transfer of the butylamine moiety of spermidine to the epsilon-amino group of a specific lysine residue of the eIF-5A precursor protein to form the intermediate deoxyhypusine residue.
 
   
 0.706
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.
     
 0.684
argC
N-acetyl-gamma-glutamyl-phosphate reductase (argC); Catalyzes the NADPH-dependent reduction of N-acetyl-5- glutamyl phosphate to yield N-acetyl-L-glutamate 5-semialdehyde. Belongs to the NAGSA dehydrogenase family. Type 1 subfamily.
