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

fumBAnaerobic 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. (548 aa)    
Predicted Functional Partners:
mdh
Malate dehydrogenase, NAD(P)-binding; Catalyzes the reversible oxidation of malate to oxaloacetate.
  
 
 0.991
fumC
Fumarate hydratase (fumarase C),aerobic Class II; Involved in the TCA cycle. FumC seems to be a backup enzyme for FumA under conditions of iron limitation and oxidative stress. Catalyzes the stereospecific interconversion of fumarate to L-malate. Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
  
 
 0.988
dcuB
C4-dicarboxylate transporter, anaerobic; Responsible for the transport of C4-dicarboxylates from the periplasm across the inner membrane; Belongs to the DcuA/DcuB transporter (TC 2.A.13.1) family.
  
  
 0.984
gltA
Citrate synthase; Protein involved in tricarboxylic acid cycle and anaerobic respiration; Belongs to the citrate synthase family.
  
 
 0.969
maeA
Malate dehydrogenase, decarboxylating, NAD-requiring; NAD-linked malate dehydrogenase (malic enzyme); Protein involved in gluconeogenesis.
  
 
 0.958
maeB
Malic enzyme: putative oxidoreductase/phosphotransacetylase; Putative multimodular enzyme; In the N-terminal section; belongs to the malic enzymes family.
   
 0.957
ydhZ
Uncharacterized protein; In vitro catalyzes the addition of water to fumarate, forming malate. Cannot catalyze the reverse reaction. Cannot use the cis-isomer maleate as substrate.
     
 0.950
mqo
Malate dehydrogenase, FAD/NAD(P)-binding domain; Protein involved in tricarboxylic acid cycle.
     
 0.948
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.
