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

icdIsocitrate dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (423 aa)    
Predicted Functional Partners:
citB
Aconitate hydratase (aconitase); Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles. Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. Also catalyzes the rehydration of 2- methyl-cis-aconitate to produce 2-methylisocitrate. The apo form of AcnA functions as a RNA-binding regulatory protein which plays a role in the regulation of citrate concentration and in the sporulation. To prevent the accumulation of excessive levels of citrate, it binds near the 5' end of the citZ mRNA, decreasing its stability and thereby limiting the conce [...]

mdh
Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate.
 
 
 0.999
citZ
Citrate synthase II; Might regulate the synthesis and function of enzymes involved in later enzymatic steps of Krebs cycle. Loss in activity results in sporulation defect; Belongs to the citrate synthase family.
 
 
 0.998
odhA
2-oxoglutarate dehydrogenase (E1 subunit); E1 component of the 2-oxoglutarate dehydrogenase (OGDH) complex which catalyzes the decarboxylation of 2-oxoglutarate, the first step in the conversion of 2-oxoglutarate to succinyl-CoA and CO(2).
   
 
 0.994
citA
Citrate synthase I; Might regulate the synthesis and function of enzymes involved in later enzymatic steps of Krebs cycle. Loss in activity results in sporulation defect; Belongs to the citrate synthase family.
 
 
 0.993
mmgD
2-methylcitrate synthase/citrate synthase III; Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles. Has both 2-methylcitrate synthase and citrate synthase activities. Catalyzes the condensation of propionyl-CoA and oxaloacetate to yield 2-methylcitrate (2-MC) and CoA, and the condensation of acetyl-CoA and oxaloacetate to yield citrate and CoA. Has 2.3-fold higher activity as a 2-methylcitrate synthase. Catalyzes the formation of either (2S,3R)- or (2R,3S)-2-methylcitrate.
 
 
 0.992
sucC
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.
 
  
 0.982
sucD
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.

gudB
Cryptic glutamate dehydrogenase; GudB seems to be intrinsically inactive, however spontaneous mutations removing a 9-bp direct repeat within the wild-type gudB sequence activated the GudB protein and allowed more-efficient utilization of amino acids of the glutamate family. This insertion presumably causes severe destabilization of the fold of the protein, leading to an inactive enzyme that is very quickly degraded. The cryptic GudB serves as a buffer that may compensate for mutations in the rocG gene and that can also be decryptified for the utilization of glutamate as a single carbon [...]

sdhB
Succinate dehydrogenase (iron-sulfur protein); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
