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

mtnP5'-methylthioadenosine phosphorylase; 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. (291 aa)    
Predicted Functional Partners:
mtnA
Putative translation initiation factor EIF-2b subunit 1; Catalyzes the interconversion of methylthioribose-1-phosphate (MTR-1-P) into methylthioribulose-1-phosphate (MTRu-1-P).
 
 
 0.984
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
 
 0.944
MAE_15220
6-phosphogluconate dehydrogenase; Catalyzes the oxidative decarboxylation of 6-phosphogluconate to ribulose 5-phosphate and CO(2), with concomitant reduction of NADP to NADPH.
 
    
 0.858
mtnD
Acireductone dioxygenase; 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.
   
 
 0.774
mtnW
2,3-diketo-5-methylthiopentyl-1-phosphate enolase; Catalyzes the enolization of 2,3-diketo-5-methylthiopentyl-1- phosphate (DK-MTP-1-P) into 2-hydroxy-3-keto-5-methylthiopentenyl-1- phosphate (HK-MTPenyl-1-P); Belongs to the RuBisCO large chain family. Type IV subfamily.
     
 0.703
speE
Spermine 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.
  
 
 0.648
guaA
GMP synthetase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.571
mtnX
Haloacid dehalogenase-like hydrolase; Dephosphorylates 2-hydroxy-3-keto-5-methylthiopentenyl-1- phosphate (HK-MTPenyl-1-P) yielding 1,2-dihydroxy-3-keto-5- methylthiopentene (DHK-MTPene).
      
 0.571
ureB
Urease beta subunit; Belongs to the urease beta subunit family.
       0.550
ureA
Urease gamma subunit; Belongs to the urease gamma subunit family.
       0.511
