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

speDS-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. (279 aa)    
Predicted Functional Partners:
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.

MCA1034
Conserved hypothetical protein; Identified by similarity to OMNI:NMB0869; match to protein family HMM PF01564.
 
 
 0.982
metK-1
S-adenosylmethionine synthetase; 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.
    
 0.915
metK-2
S-adenosylmethionine synthetase; Identified by match to protein family HMM PF00438; match to protein family HMM PF02772; match to protein family HMM PF02773; match to protein family HMM TIGR01034; Belongs to the AdoMet synthase family.
    
 0.915
MCA1616
C-5 cytosine-specific DNA methylase family protein; Identified by match to protein family HMM PF00145; match to protein family HMM TIGR00675.
     
  0.900
MCA1750
OsmC/Ohr family protein; Identified by similarity to OMNI:NTL03PA00654; match to protein family HMM PF02566.
       0.678
mtnD
Dioxygenase, ARD/ARD' family; Catalyzes 2 different reactions between oxygene and the acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene) depending upon the metal bound in the active site. Fe-containing acireductone dioxygenase (Fe-ARD) produces formate and 2-keto-4- methylthiobutyrate (KMTB), the alpha-ketoacid precursor of methionine in the methionine recycle pathway. Ni-containing acireductone dioxygenase (Ni-ARD) produces methylthiopropionate, carbon monoxide and formate, and does not lie on the methionine recycle pathway.

mtnB
Conserved hypothetical protein; Catalyzes the dehydration of methylthioribulose-1-phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P). Belongs to the aldolase class II family. MtnB subfamily.
