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

SFK46833.1Methylthioadenosine phosphorylase; Purine nucleoside phosphorylase which is highly specific for 6-oxopurine nucleosides. Cleaves guanosine or inosine to respective bases and sugar-1-phosphate molecules. Involved in purine salvage. (248 aa)    
Predicted Functional Partners:
mtaD
5-methylthioadenosine/S-adenosylhomocysteine deaminase; Catalyzes the deamination of 5-methylthioadenosine and S- adenosyl-L-homocysteine into 5-methylthioinosine and S-inosyl-L- homocysteine, respectively. Is also able to deaminate adenosine. Belongs to the metallo-dependent hydrolases superfamily. MTA/SAH deaminase family.
 
 0.971
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
 
 0.967
SFK46813.1
Hypoxanthine phosphoribosyltransferase.
  
 0.966
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; Belongs to the spermidine/spermine synthase family.
 
 
 0.923
SFK29777.1
Hopanoid-associated phosphorylase.
    
 0.898
ligA
DNA ligase (NAD+); DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA; Belongs to the NAD-dependent DNA ligase family. LigA subfamily.
       0.837
def
Peptide deformylase; Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions.
       0.837
SFK15129.1
Spermidine synthase.
 
 
 0.741
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
 
 0.686
SFK56132.1
L-fuculose-phosphate aldolase.
  
 
 0.684
