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

pykAPyruvate kinase II, glucose stimulated; Protein involved in glycolysis, fermentation and anaerobic respiration. (480 aa)    
Predicted Functional Partners:
eno
Enolase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis. It is also a component of the RNA degradosome, a multi-enzyme complex involved in RNA processing and messenger RNA degradation. Its interaction with RNase E is important for the turnover of mRNA, in particular on transcripts encoding enzymes of energy-generating metabolic routes. Its presence in the degradosome is required for the response to excess phosphosugar. May play a regulatory role in the degradation of specific RNAs, [...]
  
 0.994
pgi
Glucosephosphate isomerase; Protein involved in glycolysis and gluconeogenesis; Belongs to the GPI family.
 
 
 0.991
ppsA
Phosphoenolpyruvate synthase; Catalyzes the phosphorylation of pyruvate to phosphoenolpyruvate.
     
 0.982
maeB
Malic enzyme: putative oxidoreductase/phosphotransacetylase; Putative multimodular enzyme; In the N-terminal section; belongs to the malic enzymes family.
  
 0.982
pck
Phosphoenolpyruvate carboxykinase [ATP]; Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA. Belongs to the phosphoenolpyruvate carboxykinase (ATP) family.
   
 
 0.982
ppc
Phosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle.
   
 
 0.980
maeA
Malate dehydrogenase, decarboxylating, NAD-requiring; NAD-linked malate dehydrogenase (malic enzyme); Protein involved in gluconeogenesis.
  
 0.969
zwf
Glucose-6-phosphate 1-dehydrogenase; Catalyzes the oxidation of glucose 6-phosphate to 6- phosphogluconolactone; Belongs to the glucose-6-phosphate dehydrogenase family.
  
 
 0.969
tktA
Transketolase 1, thiamine triphosphate-binding; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Thus, catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose- 5-phosphate.
  
 0.968
pgk
Phosphoglycerate kinase; Protein involved in glycolysis and gluconeogenesis; Belongs to the phosphoglycerate kinase family.
