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.

ABO_1877Ham1 family protein; Identified by match to TIGR protein family HMMTIGR00042 InterPro: Ham1 family; Family membership. (184 aa)    
Predicted Functional Partners:
ABO_1876
SIR2 family protein; NAD-dependent protein deacetylases, SIR2 family; SIR2-like transcriptional silencer protein identified by match to PFAM protein family HMMPF02146; Family membership.
 
   0.982
dut
Deoxyuridine 5-triphosphate nucleotidohydrolase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
  
 0.935
guaA-2
GMP synthase (glutamine-hydrolysing); Catalyzes the synthesis of GMP from XMP.
  
 
 0.932
guaB
Inosine-5'-phosphate 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.
  
 0.924
purA
Adenylosuccinate synthase; 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.
  
 0.917
ndk
Nucleoside-diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
  0.915
guaA
(glutamine amidotransferase class I) identified by match to TIGR protein family HMMTIGR00888; Family membership.
 
 
  0.914
ABO_2578
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.
  
  
  0.914
purH
(phosphoribosylaminoimidazolecarboxamideformyltrans feras e/IMP cyclohydrolase) identified by sequence similarity; putative; High confidence in function and specificity.
   
 
 0.910
hpt
Hypoxanthine phosphoribosyltransferase; Identified by sequence similarity; putative InterPro: Phosphoribosyl transferase; High confidence in function and specificity.
