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

mtnBifunctional Mta/Sah nucleosidase Mtn; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. Belongs to the PNP/UDP phosphorylase family. MtnN subfamily. (251 aa)    
Predicted Functional Partners:
pnp
5'-methylthioadenosine phosphorylase, Pnp; Catalyzes the reversible phosphorylation of S-methyl-5'- thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates; Belongs to the PNP/MTAP phosphorylase family. MTAP subfamily.
    
 0.979
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.
    
 0.945
sahH
Adenosylhomocysteinase SahH; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
    
 0.918
MMAR_3921
Conserved hypothetical phage DNA methylase; Function unknown; possible role in phage DNA restriction modification system.
    
  0.904
bioB
Biotin synthase BioB; Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.
     
 0.783
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase HisA; Involved in both the histidine and tryptophan biosynthetic pathways; Belongs to the HisA/HisF family.
  
  
 0.743
guaA
GMP synthase, GuaA; Catalyzes the synthesis of GMP from XMP.
 
  
 0.576
MMAR_0249

   0.567
gltB
Ferredoxin-dependent glutamate synthase [NADPH] (large subunit) GltB; Probably involved in glutamate biosynthesis [catalytic activity: 2 L-glutamate + NADP(+) = L-glutamine + 2-oxoglutarate + NADPH].
     
 0.548
fas
Involved in lipid metabolism. fatty acid synthase catalyzes the formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH.
