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.

purHBifunctional purine biosynthesis protein PurH;includes: Phosphoribosylaminoimidazolecarboxamide formyltransferase; IMP cyclohydrolase. (536 aa)    
Predicted Functional Partners:
purN
Putative 5'-phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
 0.999
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.997
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
 0.995
glyA
Serine hydroxymethyltransferase 1; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
 0.990
ACP25285.1
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.990
fhs
Formate-tetrahydrofolate ligase; Belongs to the formate--tetrahydrofolate ligase family.
  
 0.988
purD
Phosphoribosylamine--glycine ligase; GARS; glycinamideribonucleotide synthetase; phosphoribosylglycinamide synthetase; Belongs to the GARS family.
 
 
 0.987
purM
Phosphoribosylformylglycinamidine cyclo-ligase; AIRS; Phosphoribosyl-aminoimidazole synthetase; AIR synthase.
 
  
 0.987
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase (SAICAR synthetase) PurC.
 
 
 0.987
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
