APA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"APA1" - Diadenosine 5',5''-P1,P4-tetraphosphate phosphorylase I (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

APA1Diadenosine 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)

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)
       
    0.986
MET22
Bisphosphate-3’-nucleotidase, involved in salt tolerance and methionine biogenesis; dephosphorylates 3’-phosphoadenosine-5’-phosphate and 3’-phosphoadenosine-5’-phosphosulfate, intermediates of the sulfate assimilation pathway; Converts adenosine 3’-phosphate 5’-phosphosulfate (PAPS) to adenosine 5’-phosphosulfate (APS) and 3’(2’)-phosphoadenosine 5’- phosphate (PAP) to AMP. Regulates the flux of sulfur in the sulfur-activation pathway by converting PAPS to APS. Involved in salt tolerance. Confers resistance to lithium (357 aa)

CYC1
Cytochrome c, isoform 1; electron carrier of the mitochondrial intermembrane space that transfers electrons from ubiquinone-cytochrome c oxidoreductase to cytochrome c oxidase during cellular respiration; Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain (109 aa)
         
    0.900
CYC7
Cytochrome c isoform 2, expressed under hypoxic conditions; electron carrier of the mitochondrial intermembrane space that transfers electrons from ubiquinone-cytochrome c oxidoreductase to cytochrome c oxidase during cellular respiration; Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain (113 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)
