STRINGSTRING
DUG3 protein (Saccharomyces cerevisiae) - STRING interaction network
"DUG3" - Probable glutamine amidotransferase, forms a complex with Dug1p and Dug2p to degrade glutathione 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

DUG3Probable glutamine amidotransferase, forms a complex with Dug1p and Dug2p to degrade glutathione (GSH) and other peptides containing a gamma-glu-X bond in an alternative pathway to GSH degradation by gamma-glutamyl transpeptidase (Ecm38p); Component of the GSH degradosomal complex involved in the degradation of glutathione (GSH) and other peptides containing a gamma-glu-X bond (357 aa)    
Predicted Functional Partners:
DUG2
Probable di- and tri-peptidase; forms a complex with Dug1p and Dug3p to degrade glutathione (GSH) and other peptides containing a gamma-glu-X bond in an alternative pathway to GSH degradation by gamma-glutamyl transpeptidase (Ecm38p); Component of the GSH degradosomal complex involved in the degradation of glutathione (GSH) and other peptides containing a gamma-glu-X bond (878 aa)

DUG1
Cys-Gly metallo-di-peptidase; forms a complex with Dug2p and Dug3p to degrade glutathione (GSH) and other peptides containing a gamma-glu-X bond in an alternative pathway to GSH degradation by gamma-glutamyl transpeptidase (Ecm38p); Catalytic component of the GSH degradosomal complex involved in the degradation of glutathione (GSH) and other peptides containing a gamma-glu-X bond. Functions also in a DUG2- DUG3-independent manner as a dipeptidase with high specificity for Cys-Gly and no activity toward tri- or tetrapeptides (481 aa)

IMD2
Inosine monophosphate dehydrogenase, catalyzes the rate-limiting step in GTP biosynthesis, expression is induced by mycophenolic acid resulting in resistance to the drug, expression is repressed by nutrient limitatio; 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. In contrast to the other IMPDH alleles IMD3 and IMD4, the enzymatic activity of IMD2 seems to be intrinsically drug resistant (523 aa)

GTO3
Omega class glutathione transferase; putative cytosolic localization; Active as ’1-Cys’ thiol transferase against beta- hydroxyethyl disulfide (HED), as dehydroascorbate reductase and as dimethylarsinic acid reductase, while not active against the standard GST substrate 1-chloro-2,4-dinitrobenzene (CDNB) (366 aa)
     
 
  0.655
CYS4
Cystathionine beta-synthase, catalyzes synthesis of cystathionine from serine and homocysteine, the first committed step in cysteine biosynthesis; responsible for hydrogen sulfide generation; mutations in human ortholog cause homocystinuria (507 aa)
         
  0.632
GEF1
Voltage-gated chloride channel localized to the golgi, the endosomal system, and plasma membrane, and involved in cation homeostasis; highly homologous to vertebrate voltage-gated chloride channels; Anion/proton exchange transporter involved in iron and copper cation homeostasis. Involved in intracellular iron metabolism during growth on fermentable and non fermentable carbon sources. Required for proper copper-loading and maturation of multicopper oxidase FET3. Important for adjusting intracellular compartment pH to more alkaline pH under iron limitation. May also transport chloride i [...] (779 aa)

SDS23
One of two S. cerevisiae homologs (Sds23p and Sds24p) of the S. pombe Sds23 protein, which is implicated in APC/cyclosome regulation; involved in cell separation during budding; Involved in DNA replication and cell separation during budding (527 aa)
     
 
    0.612
SDS24
One of two S. cerevisiae homologs (Sds23p and Sds24p) of the S. pombe Sds23 protein, which is implicated in APC/cyclosome regulation; involved in cell separation during budding; may play an indirect role in fluid-phase endocytosis; Involved in DNA replication and cell separation during budding (527 aa)
     
 
    0.612
GTO1
Omega-class glutathione transferase; induced under oxidative stress; putative peroxisomal localization; Active as ’1-Cys’ thiol transferase against beta- hydroxyethyl disulfide (HED), as dehydroascorbate reductase and as dimethylarsinic acid reductase, while not active against the standard GST substrate 1-chloro-2,4-dinitrobenzene (CDNB) (356 aa)
     
 
  0.606
GUA1
GMP synthase; highly conserved enzyme that catalyzes the second step in the biosynthesis of GMP from inosine 5’-phosphate (IMP); transcription is not subject to regulation by guanine but is negatively regulated by nutrient starvation; reduction-of-f /.../n mutation gua1-G388D causes changes in cellular guanine nucleotide pools, defects in general protein synthesis, and impaired translation of GCN4 mRNA (525 aa)
