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

M446_6558Phosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. (920 aa)    
Predicted Functional Partners:
sucD-2
succinyl-CoA synthetase, alpha subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.
 
  
 0.923
eno
Phosphopyruvate hydratase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.
   
 
 0.921
eno-2
Phosphopyruvate hydratase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.
   
 
 0.921
pckA
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.
     
 0.920
mdh
Malate dehydrogenase, NAD-dependent; Catalyzes the reversible oxidation of malate to oxaloacetate. Belongs to the LDH/MDH superfamily. MDH type 3 family.
     
 0.920
M446_2710
KEGG: mex:Mext_2891 pyruvate, phosphate dikinase; TIGRFAM: pyruvate, phosphate dikinase; PFAM: PEP-utilizing protein; pyruvate phosphate dikinase PEP/pyruvate-binding; PEP-utilising protein mobile region; Belongs to the PEP-utilizing enzyme family.
     
 0.920
sucC-2
succinyl-CoA synthetase, beta subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.
 
  
 0.918
M446_1812
PFAM: glutamine amidotransferase class-II; glutamate synthase alpha subunit domain protein; ferredoxin-dependent glutamate synthase; glutamate synthase; KEGG: mex:Mext_3266 glutamate synthase (ferredoxin).
 
  
 0.912
M446_5207
KEGG: mex:Mext_2744 pyruvate kinase; TIGRFAM: pyruvate kinase; PFAM: Pyruvate kinase barrel; Pyruvate kinase alpha/beta; Belongs to the pyruvate kinase family.
     
 0.912
M446_6176
KEGG: bbt:BBta_5564 pyruvate kinase; TIGRFAM: pyruvate kinase; PFAM: Pyruvate kinase barrel; Pyruvate kinase alpha/beta; Belongs to the pyruvate kinase family.
