STRINGSTRING
HNT2 protein (Saccharomyces cerevisiae) - STRING interaction network
"HNT2" - Dinucleoside triphosphate hydrolase in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

HNT2Dinucleoside triphosphate hydrolase; has similarity to the tumor suppressor FHIT and belongs to the histidine triad (HIT) superfamily of nucleotide-binding proteins; Cleaves A-5’-PPP-5’A to yield AMP and ADP. Can cleave all dinucleoside polyphosphates, provided the phosphate chain contains at least 3 phosphates and that 1 of the 2 bases composing the nucleotide is a purine. Is most effective on dinucleoside triphosphates. Negatively regulates intracellular dinucleoside polyphosphate levels, which elevate following heat shock (217 aa)    
Predicted Functional Partners:
APA2
Diadenosine 5’,5’’-P1,P4-tetraphosphate phosphorylase II (AP4A phosphorylase), involved in catabolism of bis(5’-nucleosidyl) tetraphosphates; has similarity to Apa1p; Ap4A phosphorylase catalyzes the phosphorolytic degradation of bis(5’-adenosyl) tetraphosphate (Ap4A) into ADP and ATP. Can also use other Np4N’ nucleotides (where N and N’ stand for A,C,G or U) as substrates, but prefers A-containing substrates. Cannot catalyze the reverse reaction. Additionally, this enzyme can also catalyze the phosphorolytic degradation of adenosine 5’-phosphosulfate (AMPS) into ADP and sulfate, the r [...] (325 aa)

APA1
Diadenosine 5’,5’’-P1,P4-tetraphosphate phosphorylase I (AP4A phosphorylase), involved in catabolism of bis(5’-nucleosidyl) tetraphosphates; has similarity to Apa2p; Ap4A phosphorylase catalyzes the phosphorolytic degradation of bis(5’-adenosyl) tetraphosphate (Ap4A) into ADP and ATP. Can also use other Np4N’ nucleotides (where N and N’ stand for A,C,G or U) as substrates with equal efficiency. Cannot catalyze the reverse reaction. Additionally, this enzyme can also catalyze the phosphorolytic degradation of adenosine 5’- phosphosulfate (AMPS) into ADP and sulfate, the reversible excha [...] (321 aa)

SPE2
S-adenosylmethionine decarboxylase, required for the biosynthesis of spermidine and spermine; cells lacking Spe2p require spermine or spermidine for growth in the presence of oxygen but not when grown anaerobically; S-adenosylmethionine decarboxylase is essential for normal growth, sporulation, maintenance of ds-RNA virus, biosynthesis of spermine and spermidine (396 aa)
       
      0.748
HNT3
DNA 5’ AMP hydrolase involved in DNA repair; member of the histidine triad (HIT) superfamily of nucleotide-binding proteins; homolog of Aprataxin, a Hint related protein that is mutated in individuals with ataxia with oculomotor apraxia; DNA-binding protein involved in single-strand DNA break repair, double-strand DNA break repair and base excision repair. Resolves abortive DNA ligation intermediates formed either at base excision sites, or when DNA ligases attempt to repair non- ligatable breaks induced by reactive oxygen species. Catalyzes the release of adenylate groups covalently l [...] (217 aa)

MSF1
Mitochondrial phenylalanyl-tRNA synthetase, active as a monomer, unlike the cytoplasmic subunit which is active as a dimer complexed to a beta subunit dimer; similar to the alpha subunit of E. coli phenylalanyl-tRNA synthetase; Is responsible for the charging of tRNA(Phe) with phenylalanine in mitochondrial translation (469 aa)
   
 
  0.633
HIS4
Multifunctional enzyme containing phosphoribosyl-ATP pyrophosphatase, phosphoribosyl-AMP cyclohydrolase, and histidinol dehydrogenase activities; catalyzes the second, third, ninth and tenth steps in histidine biosynthesis (799 aa)
         
  0.592
HIS7
Imidazole glycerol phosphate synthase; glutamine amidotransferase-cyclase that catalyzes the fifth step of histidine biosynthesis and also produces 5-aminoimidazole-4-carboxamide ribotide (AICAR), a purine precursor; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The glutamine amidotransferase domain provides the ammonia necessary to the cyclase domain to produce IGP and AICAR from PRFAR (552 aa)
