STRINGSTRING
AHP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"AHP1" - Thiol-specific peroxiredoxin, reduces hydroperoxides to protect against oxidative damage 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

AHP1Thiol-specific peroxiredoxin, reduces hydroperoxides to protect against oxidative damage; function in vivo requires covalent conjugation to Urm1p; Thiol-specific antioxidant protein with alkyl hydroperoxidase activity. Involved in osmotic stress resistance and detoxification of the cell. Preferentially eliminates organic peroxides rather than H(2)O(2). Involved in cellular Mn(2+) homeostasis (176 aa)    
Predicted Functional Partners:
TRX2
Cytoplasmic thioredoxin isoenzyme of the thioredoxin system which protects cells against oxidative and reductive stress, forms LMA1 complex with Pbi2p, acts as a cofactor for Tsa1p, required for ER-Golgi transport and vacuole inheritance; Participates as a hydrogen donor in redox reactions through the reversible oxidation of its active center dithiol to a disulfide, accompanied by the transfer of 2 electrons and 2 protons. It is involved in many cellular processes, including deoxyribonucleotide synthesis, repair of oxidatively damaged proteins, protein folding, sulfur metabolism, and r [...] (104 aa)

TSA1
Thioredoxin peroxidase, acts as both a ribosome-associated and free cytoplasmic antioxidant; self-associates to form a high-molecular weight chaperone complex under oxidative stress; deletion results in mutator phenotype; Physiologically important antioxidant which constitutes an enzymatic defense against sulfur-containing radicals. Can provide protection against a thiol-containing oxidation system but not against an oxidation system without thiol (196 aa)
     
 
  0.986
PRX1
Mitochondrial peroxiredoxin (1-Cys Prx) with thioredoxin peroxidase activity, has a role in reduction of hydroperoxides; reactivation requires Trr2p and glutathione; induced during respiratory growth and oxidative stress; phosphorylated; Has a thioredoxin peroxidase activity with a role in reduction of hydroperoxides (261 aa)
     
 
  0.962
URM1
Ubiquitin-like protein involved in thiolation of cytoplasmic tRNAs; receives sulfur from the E1-like enzyme Uba4p and transfers it to tRNA; also functions as a protein tag with roles in nutrient sensing and oxidative stress response; Acts as a sulfur carrier required for 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). Serves as sulfur donor in tRNA 2- thiolation reaction by being thiocarboxylated (-COSH) at its C- terminus by UBA4. The sulfur is then transferred to tRNA to form 2-thiolation of mcm(5)S(2)U. Prior mcm(5) tRNA modifica [...] (99 aa)
       
  0.961
TSA2
Stress inducible cytoplasmic thioredoxin peroxidase; cooperates with Tsa1p in the removal of reactive oxygen, nitrogen and sulfur species using thioredoxin as hydrogen donor; deletion enhances the mutator phenotype of tsa1 mutants; Reduces peroxides. May play an important role in eliminating peroxides generated during metabolism (By similarity) (196 aa)

CTT1
Cytosolic catalase T, has a role in protection from oxidative damage by hydrogen peroxide; Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide (562 aa)

CTA1
Catalase A, breaks down hydrogen peroxide in the peroxisomal matrix formed by acyl-CoA oxidase (Pox1p) during fatty acid beta-oxidation; Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide (515 aa)

TRX3
Mitochondrial thioredoxin, highly conserved oxidoreductase required to maintain the redox homeostasis of the cell, forms the mitochondrial thioredoxin system with Trr2p, redox state is maintained by both Trr2p and Glr1p (127 aa)

GRX3
Hydroperoxide and superoxide-radical responsive glutathione-dependent oxidoreductase; monothiol glutaredoxin subfamily member along with Grx4p and Grx5p; protects cells from oxidative damage; Monothiol glutaredoxin involved in the biogenesis of iron-sulfur clusters (By similarity). Binds one iron-sulfur cluster per dimer. The iron-sulfur cluster is bound between subunits, and is complexed by a bound glutathione and a cysteine residue from each subunit (Probable) (285 aa)
