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.

purAAdenylosuccinate 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. (397 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase; Similar to GB:AE000657 percent identity: 73.60; identified by sequence similarity; putative.
 
 0.999
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.
 
 
 0.993
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Similar to GB:AE000657 percent identity: 61.39; identified by sequence similarity; putative.
  
 0.987
pyrBI
Aspartate carbamoyltransferase, catalytic and regulatory chains; Similar to PID:1772605 GB:AE000512 percent identity: 100.00; identified by sequence similarity; putative; In the N-terminal section; belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
 
 0.977
TM_0159
Ham1 protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
 0.975
TM_0206
Hypoxanthine phosphoribosyltransferase; Similar to GB:D26185 SP:P37472 PID:467457 GB:AL009126 percent identity: 66.67; identified by sequence similarity; putative; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.972
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase; Similar to GB:L77117 PID:1592203 percent identity: 68.02; identified by sequence similarity; putative; Belongs to the SAICAR synthetase family.
  
 0.969
argG
Argininosuccinate synthase; Similar to SP:P16460 PID:192065 PID:192066 PID:309111 PID:553871 percent identity: 76.79; identified by sequence similarity; putative; Belongs to the argininosuccinate synthase family. Type 1 subfamily.
  
 
 0.964
purE
Phosphoribosylaminoimidazole carboxylase, catalytic subunit; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
 
 0.961
aspC
Aspartate aminotransferase; Similar to PID:1255699 percent identity: 66.22; identified by sequence similarity; putative; Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
