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

Score
mdhMalate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate. Belongs to the LDH/MDH superfamily. MDH type 2 family. (325 aa)    
Predicted Functional Partners:
gltA
Citrate synthase; Identified by similarity to SP:Q10530; match to protein family HMM PF00285; match to protein family HMM TIGR01798; Belongs to the citrate synthase family.
  
 0.992
fumC
Fumarate hydratase; Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
  
 0.966
sucD-2
succinyl-CoA synthase, 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.
  
 0.958
sfcA
Malate oxidoreductase; Identified by similarity to SP:P26616; match to protein family HMM PF00390; match to protein family HMM PF03949.
 
 0.956
sucC-2
succinyl-CoA synthase, 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.
  
 0.951
oadA
Oxaloacetate decarboxylase, alpha subunit; Identified by match to protein family HMM PF00364; match to protein family HMM PF00682; match to protein family HMM PF02436; match to protein family HMM TIGR01108.
    
 0.950
oadB
Oxaloacetate decarboxylase, beta subunit; Catalyzes the decarboxylation of oxaloacetate coupled to Na(+) translocation; Belongs to the GcdB/MmdB/OadB family.
     
 0.931
oadC
Oxaloacetate decarboxylase, gamma subunit; Catalyzes the decarboxylation of oxaloacetate coupled to Na(+) translocation.
     
 0.931
MCA0769
Pyruvate ferredoxin/flavodoxin oxidoreductase family protein; Identified by similarity to SP:P52647; match to protein family HMM PF00037; match to protein family HMM PF01558; match to protein family HMM PF01855; match to protein family HMM PF02775; match to protein family HMM TIGR02176.
  
  
 0.920
MCA2202
Aspartate aminotransferase; Identified by similarity to SP:P23034; match to protein family HMM PF00155.
  
 0.916
