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.

guaAGMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP. (529 aa)    
Predicted Functional Partners:
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.
 0.999
purL
Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
  
  
 0.985
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.974
Hhal_1260
PFAM: phosphoribosyltransferase; KEGG: aeh:Mlg_1328 phosphoribosyltransferase.
  
 
 0.969
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
 
 0.969
surE
5'-nucleotidase / 3'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.968
argS
KEGG: aeh:Mlg_2774 arginyl-tRNA synthetase; TIGRFAM: arginyl-tRNA synthetase.
   
  
 0.965
lysS
TIGRFAM: lysyl-tRNA synthetase; PFAM: tRNA synthetase, class II (G, H, P and S); tRNA synthetase, class II (D, K and N); nucleic acid binding, OB-fold, tRNA/helicase-type; KEGG: aeh:Mlg_1804 lysyl-tRNA synthetase; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.960
Hhal_0972
Non-canonical purine NTP pyrophosphatase, rdgB/HAM1 family; 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.
 
 
 0.959
purH
IMP cyclohydrolase; KEGG: aeh:Mlg_0611 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: MGS domain protein; AICARFT/IMPCHase bienzyme, formylation region.
