STRINGSTRING
APA2 protein (Saccharomyces cerevisiae) - STRING interaction network
"APA2" - Diadenosine 5',5''-P1,P4-tetraphosphate phosphorylase II (AP4A phosphorylase), involved in catabolism of bis(5'-nucleosidyl) tetraphosphates 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

APA2Diadenosine 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)

HNT2
Dinucleoside 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)

MET3
ATP sulfurylase, catalyzes the primary step of intracellular sulfate activation, essential for assimilatory reduction of sulfate to sulfide, involved in methionine metabolism; Catalyzes the first intracellular reaction of sulfate assimilation, forming adenosine-5’-phosphosulfate (APS) from inorganic sulfate and ATP. Plays an important role in sulfate activation as a component of the biosynthesis pathway of sulfur- containing amino acids (511 aa)
