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

pycAPyruvate carboxylase; Catalyzes a 2-step reaction, involving the ATP-dependent carboxylation of the covalently attached biotin in the first step and the transfer of the carboxyl group to pyruvate in the second, leading to oxaloacetate production. Fulfills an anaplerotic function in B.subtilis as it is necessary for growth on glucose, but is not required for sporulation. (1148 aa)    
Predicted Functional Partners:
pckA
Phosphoenolpyruvate carboxykinase; Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA.
  
 
 0.993
pyk
Pyruvate kinase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; In the C-terminal section; belongs to the PEP-utilizing enzyme family.
   
 0.987
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.
  
 0.983
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.
  
 0.982
mdh
Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate.
  
 0.978
ldh
L-lactate dehydrogenase; Catalyzes the conversion of lactate to pyruvate.
  
 0.977
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.
  
 0.971
pdhA
Pyruvate dehydrogenase (E1 alpha subunit); The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3).
  
 
 0.957
ytsJ
NADP-dependent malic enzyme (conversion of malate into pyruvate); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
   
 0.956
birA
Biotin acetyl-CoA-carboxylase ligase and biotin regulon repressor; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
