STRINGSTRING
GDB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"GDB1" - Glycogen debranching enzyme containing glucanotranferase and alpha-1,6-amyloglucosidase activities, required for glycogen degradation 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

GDB1Glycogen debranching enzyme containing glucanotranferase and alpha-1,6-amyloglucosidase activities, required for glycogen degradation; phosphorylated in mitochondria; activity is inhibited by Igd1p; Multifunctional enzyme acting as 1,4-alpha-D-glucan-1,4- alpha-D-glucan 4-alpha-D-glycosyltransferase and amylo-1,6- glucosidase in glycogen degradation (1536 aa)    
Predicted Functional Partners:
GPH1
Glycogen phosphorylase required for the mobilization of glycogen; non-essential; regulated by cyclic AMP-mediated phosphorylation; expression is regulated by stress-response elements and by the HOG MAP kinase pathway; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (902 aa)
   
 
  0.999
GSY2
Glycogen synthase, similar to Gsy1p; expression induced by glucose limitation, nitrogen starvation, heat shock, and stationary phase; activity regulated by cAMP-dependent, Snf1p and Pho85p kinases as well as by the Gac1p-Glc7p phosphatase; Transfers the glycosyl residue from UDP-Glc to the non- reducing end of alpha-1,4-glucan. Is believed to regulate the synthesis of glycogen (705 aa)
   
  0.999
GLC3
Glycogen branching enzyme, involved in glycogen accumulation; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm in a punctate pattern (704 aa)
   
 
  0.999
GSY1
Glycogen synthase with similarity to Gsy2p, the more highly expressed yeast homolog; expression induced by glucose limitation, nitrogen starvation, environmental stress, and entry into stationary phase; Transfers the glycosyl residue from UDP-Glc to the non- reducing end of alpha-1,4-glucan. Is believed to regulate the synthesis of glycogen (708 aa)
   
 
  0.991
SGA1
Intracellular sporulation-specific glucoamylase involved in glycogen degradation; induced during starvation of a/a diploids late in sporulation, but dispensable for sporulation (549 aa)
   
 
  0.980
PGM2
Phosphoglucomutase, catalyzes the conversion from glucose-1-phosphate to glucose-6-phosphate, which is a key step in hexose metabolism; functions as the acceptor for a Glc-phosphotransferase; Major phosphoglucomutase isozyme that catalyzes the reversible interconversion of glucose 1-phosphate and glucose 6- phosphate (PubMed-5784209). Constitutes about 80-90% of the phosphoglucomutase activity in the cell (PubMed-14264884, PubMed-5231755). Key enzyme in hexose metabolism. The forward reaction is an essential step in the energy metabolism of galactose since the product of the galactose [...] (569 aa)

TSL1
Large subunit of trehalose 6-phosphate synthase (Tps1p)/phosphatase (Tps2p) complex, which converts uridine-5’-diphosphoglucose and glucose 6-phosphate to trehalose, similar to Tps3p and may share function; mutant has aneuploidy tolerance; Regulatory subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6- phosphate and UDP-glucose in a two step process. May stabilize the trehalose synthase complex, and confer sensitivity to physiological concentrations of phosphate and to fructose 6- phosphate (1098 aa)
   
   
  0.973
GAD1
Glutamate decarboxylase, converts glutamate into gamma-aminobutyric acid (GABA) during glutamate catabolism; involved in response to oxidative stress (585 aa)
     
   
  0.969
IMA4
Alpha-glucosidase with broad substrate specificity for alpha-1,4- and alpha-1,6-glucosides; member of IMA isomaltase family; not required for isomaltose utilization, but Ima4p overexpression allows the ima1 null mutant to grow on isomaltose; Alpha-glucosidase with broad substrate specificity for alpha-1,4- and alpha-1,6-glucosides. Not required for isomaltose utilization, but overexpression allows the IMA1 null mutant to grow on isomaltose (589 aa)
   
  0.968
IMA1
Major isomaltase (alpha-1,6-glucosidase) required for isomaltose utilization; has specificity for isomaltose, palatinose, and methyl-alpha-glucoside; member of the IMA isomaltase family; Major isomaltase (alpha-1,6-glucosidase) required for isomaltose utilization. Preferentially hydrolyzes isomaltose, palatinose, and methyl-alpha-glucoside, with little activity towards isomaltotriose or longer oligosaccharides. Does not hydrolyze maltose (589 aa)
