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.

Score
Ldb2200Permease; Major Facilitator Superfamily (MFS). (436 aa)    
Predicted Functional Partners:
xpt
Xanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.
  
  
 0.604
purD
ABC transporter, ATP-binding protein (fragment); Putative Cystathionine beta-lyase or Cystathionine gamma-synthase (fragment); Belongs to the GARS family.
  
  
 0.594
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
     
 0.579
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase / IMP cyclohydrolase; Bifunctional enzyme.
  
  
 0.575
purE
Phosphoribosylaminoimidazole carboxylase, catalytic subunit; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
  
 0.572
pbuX
Xanthine permease.
  
  
 0.564
purK
Phosphoribosylaminoimidazole carboxylase, ATPasesubunit; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
  
    0.549
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides; Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
  
  
 0.543
purM
Phosphoribosylformylglycinamidine cyclo-ligase.
  
  
 0.520
purL
Phosphoribosylformylglycinamidine synthase II; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist [...]
