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

ttdBL-tartrate dehydratase, subunit B; Protein involved in fermentation. (201 aa)    
Predicted Functional Partners:
ttdA
L-tartrate dehydratase, subunit A; Protein involved in fermentation.
 
 0.999
dmlA
D-malate oxidase, NAD-dependent; Catalyzes the NAD(+)-dependent oxidative decarboxylation of D-malate into pyruvate. Is essential for aerobic growth on D-malate as the sole carbon source. But is not required for anaerobic D-malate utilization, although DmlA is expressed and active in those conditions. Appears to be not able to use L-tartrate as a substrate for dehydrogenation instead of D-malate; Belongs to the isocitrate and isopropylmalate dehydrogenases family.
 
 
 0.947
ttdT
L-tartrate/succinate antiporte; Catalyzes the uptake of tartrate in exchange for intracellular succinate. Essential for anaerobic L-tartrate fermentation; Belongs to the SLC13A/DASS transporter (TC 2.A.47) family. DIT1 subfamily.
 
  
 0.945
mdh
Malate dehydrogenase, NAD(P)-binding; Catalyzes the reversible oxidation of malate to oxaloacetate.
  
 
 0.941
maeB
Malic enzyme: putative oxidoreductase/phosphotransacetylase; Putative multimodular enzyme; In the N-terminal section; belongs to the malic enzymes family.
   
 0.936
gltA
Citrate synthase; Protein involved in tricarboxylic acid cycle and anaerobic respiration; Belongs to the citrate synthase family.
    
 0.908
fumB
Anaerobic class I fumarate hydratase (fumarase B); Catalyzes the reversible hydration of fumarate to (S)-malate. Functions in the generation of fumarate for use as an anaerobic electron acceptor. To a lesser extent, also displays D-tartrate dehydratase activity, but is not able to convert (R)-malate, L-tartrate or meso-tartrate. Is required for anaerobic growth on D-tartrate. Belongs to the class-I fumarase family.
 
  
0.863
fumA
Fumarate hydratase (fumarase A), aerobic Class I; Catalyzes the reversible hydration of fumarate to (S)-malate. Functions as an aerobic enzyme in the direction of malate formation as part of the citric acid cycle. Accounts for about 80% of the fumarase activity when the bacteria grow aerobically. To a lesser extent, also displays D-tartrate dehydratase activity in vitro, but is not able to convert (R)-malate, L-tartrate or meso-tartrate. Can also catalyze the isomerization of enol- to keto-oxaloacetate.
 
  
0.851
ybiW
Putative pyruvate formate lyase; Probably shows dehydratase activity. Belongs to the glycyl radical enzyme (GRE) family.
   
 
 0.849
pflD
Putative glycine radical domain-containing pyruvate formate-lyase; Probably shows dehydratase activity. Belongs to the glycyl radical enzyme (GRE) family.
