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.

[Homology]
Score
mdhMalate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate. Belongs to the LDH/MDH superfamily. MDH type 2 family. (330 aa)    
Predicted Functional Partners:
gltA
Probable citrate synthase. Homology to gltA of s. meliloti of 69% (sprot|CISY_RHIME). Citrate synthase is a member of a small family of enzymes that can directly form a carbon-carbon bond without the presence of metal ion cofactors. It catalyses the first reaction in the Krebs' cycle: Citrate + CoA = acetyl-CoA + H2 O + oxaloacetate InterPro: Citrate synthase (IPR002020) Pfam: Citrate synthase no signal peptide no TMHs; High confidence in function and specificity.

fumB
Putative fumarate hydratase; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.
  
 
 0.994
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.

icd1
Isocitrate dehydrogenase [NADP]. Homology to icd1 of A. eutropus of 75% (trembl|Q8KLU5) Isocitrate dehydrogenase is an important enzyme of the TCA which catalyzes the reaction: isocitrate + NAD+ = 2-oxoglutarate + CO2 + NADH + H+ Pfam: Isocitrate/isopropylmalate dehydrogenase Tigrfam: prok_nadp_idh: isocitrate dehydrogenase no signal peptide no TMHs; High confidence in function and specificity.

aceB
AceB protein; Malate synthase. Homology to aceB of A. eutropus of 73% (trembl|Q8VM95). CATALYTIC ACTIVITY: Acetyl-CoA + H(2)O + glyoxylate = S-malate + CoA. Acts in the glyoxylate bypass. Pfam: Malate synthase no TMHs 1 HTH; High confidence in function and specificity.
   
 0.960
sdhA
Probable succinate dehydrogenase, flavoprotein subunit. Homology to sdhA of C. burnetii of 54% (sprot|DHSA_COXBU) Part of an enzyme complex containing four subunits: a flavoprotein, an iron-sulfur protein,cytochrome b-556 and a hydrophobic protein. CATALYTIC ACTIVITY: Succinate + acceptor = fumarate + reduced acceptor. InterPro: Fumarate reductase/succinate dehydrogenase flavoprotein N-terminal (IPR003953); Fumarate reductase/succinate dehydrogenase FAD-binding site (IPR003952); Fumarate reductase/succinate dehydrogenase, C-terminal (IPR004112) Pfam: FAD-binding domain; Fumarate reduct [...]

pykA
Pyruvate kinase (PK) catalyses the final step in glycolysis, the conversion of phosphoenolpyruvate to pyruvate with concomitant phosphorylation of ADP to ATP:ADP + phosphoenolpyruvate = ATP + pyruvate. 52% Pyruvate_kinase. Pfam:PF00224; PK; 1.PF02887; PK_C; 1. TIGRFAMs:TIGR01064; pyruv_kin; 1; High confidence in function and specificity.

Plays a key role in the conversion of malate to acetyl-CoA for efficient tricarboxylic acid cycle function in nitrogen-fixating bacteria. Tigrfam: pta: phosphotransacetylase Pfam: Malic enzyme; Phosphate acetyl/butaryltransferase no signal peptide no TMHs; High confidence in function and specificity.
  
 0.957
maeB2
Probable malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+). Homology to dme of S. meliloti of 61% (sprot|MAO1_RHIME). Required for symbiotic nitrogen fixation. Plays a key role in the conversion of malate to acetyl-CoA for efficient tricarboxylic acid cycle function in nitrogen-fixating bacteria. InterPro: Phosphate acetyl/butaryl transferase (IPR002505); Malic enzyme (IPR001891) Pfam: Malic enzyme; Phosphate acetyl/butaryl transferase Tigrfam: pta: phosphotransacetylase no signal peptide no TMHs; High confidence in function and specificity.
