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

ppcPhosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. (883 aa)    
Predicted Functional Partners:
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.
     
 0.991
gltA
Citrate synthase; Protein involved in tricarboxylic acid cycle and anaerobic respiration; Belongs to the citrate synthase family.
   
 
 0.987
ppsA
Phosphoenolpyruvate synthase; Catalyzes the phosphorylation of pyruvate to phosphoenolpyruvate.
     
 0.985
mdh
Malate dehydrogenase, NAD(P)-binding; Catalyzes the reversible oxidation of malate to oxaloacetate.
   
 
 0.983
pykF
Pyruvate kinase I (formerly F), fructose stimulated; Protein involved in glycolysis, fermentation and anaerobic respiration.
   
 
 0.982
pykA
Pyruvate kinase II, glucose stimulated; Protein involved in glycolysis, fermentation and anaerobic respiration.
   
 
 0.980
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, [...]
   
 
 0.972
aceB
Malate synthase A; Protein involved in glyoxylate cycle.
   
 
 0.964
mqo
Malate dehydrogenase, FAD/NAD(P)-binding domain; Protein involved in tricarboxylic acid cycle.
     
 0.959
glcB
Malate synthase G; Involved in the glycolate utilization. Catalyzes the condensation and subsequent hydrolysis of acetyl-coenzyme A (acetyl- CoA) and glyoxylate to form malate and CoA.
    
 0.923
