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

speHConserved 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. (112 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.
 
 
 0.999
mat
Conserved hypothetical protein; Catalyzes the formation of S-adenosylmethionine from methionine and ATP; Belongs to the AdoMet synthase 2 family.
     
 0.916
bpsA
Conserved hypothetical protein; Involved in the biosynthesis of branched-chain polyamines, which support the growth of thermophiles under high-temperature conditions. Catalyzes the sequential condensation of spermidine with the aminopropyl groups of decarboxylated S-adenosylmethionines to produce N(4)-bis(aminopropyl)spermidine via N(4)-aminopropylspermidine.
 
     0.887
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).
