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

speABiosynthetic arginine decarboxylase; Catalyzes the biosynthesis of agmatine from arginine. Belongs to the Orn/Lys/Arg decarboxylase class-II family. SpeA subfamily. (675 aa)    
Predicted Functional Partners:
argI
Arginase; Identified by sequence similarity; putative; ORF located using Blastx/Glimmer/Genemark; Belongs to the arginase family.
  
 
 0.944
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.
     
 0.896
XCC2199
Beta-alanine synthetase; Identified by sequence similarity; putative; ORF located using Blastx/Glimmer/Genemark.
 
   
 0.847
argH
Argininosuccinate lyase; Identified by sequence similarity; putative; ORF located using Blastx/Glimmer/Genemark.
     
 0.835
XCC2198
Conserved hypothetical protein; Identified by sequence similarity; putative; ORF located using Blastx/Glimmer/Genemark; Belongs to the agmatine deiminase family.
 
   
 0.772
speD
S-adenosyl methionine 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.
  
   
 0.683
lysA
Bifunctional diaminopimelate decarboxylase/aspartate kinase; Identified by sequence similarity; putative; ORF located using Blastx/Glimmer/Genemark; Belongs to the Orn/Lys/Arg decarboxylase class-II family.
  
  
 0.514
metK
Methionine adenosyltransferase; 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.
