STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

glgPGlycogen phosphorylase; 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. (815 aa)    
Predicted Functional Partners:
glgA
Glycogen synthase; Synthesizes alpha-1,4-glucan chains using ADP-glucose.
  
 0.999
glgC
Glucose-1-phosphate adenylyltransferase; Involved in the biosynthesis of ADP-glucose, a building block required for the elongation reactions to produce glycogen. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc; Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
 
 0.999
glgX
Glycogen debranching enzyme; Removes maltotriose and maltotetraose chains that are attached by 1,6-alpha-linkage to the limit dextrin main chain, generating a debranched limit dextrin. Shows only very little activity with native glycogen.
 
 0.999
glgB
1,4-alpha-glucan branching enzyme; Catalyzes the formation of the alpha-1,6-glucosidic linkages in glycogen by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position; Belongs to the glycosyl hydrolase 13 family. GlgB subfamily.
 0.999
pgm
Phosphoglucomutase; This enzyme participates in both the breakdown and synthesis of glucose; Belongs to the phosphohexose mutase family.
  
 
 0.994
malQ
4-alpha-glucanotransferase (amylomaltase); Protein involved in carbohydrate catabolic process and polysaccharide catabolic process; Belongs to the disproportionating enzyme family.
 
 0.993
amyA
Cytoplasmic alpha-amylase; Protein involved in carbohydrate catabolic process and polysaccharide catabolic process; Belongs to the glycosyl hydrolase 13 family.
  
 0.953
malS
Alpha-amylase; Since only maltooligosaccharides up to a chain length of 6 glucose units are actively transported through the cytoplasmic membrane via the membrane-bound complex of three proteins, MalF, MalG, and MalK, longer maltooligosaccharides must first be degraded by the periplasmic alpha-amylase, the MalS protein; Belongs to the glycosyl hydrolase 13 family.
  
 0.948
ptsH
Phosphohistidinoprotein-hexose phosphotransferase component of PTS system (Hpr); General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain.
   
 0.947
galU
Glucose-1-phosphate uridylyltransferase; May play a role in stationary phase survival; Belongs to the UDPGP type 2 family.
     
 0.913
