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

citZCitrate 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. (372 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.
  
 0.998
icd
Isocitrate dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
 
 
 0.998
pycA
Pyruvate 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.
  
 0.982
acsA
acetyl-CoA synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. AcsA undergoes a two-step reaction. In the first half reaction, AcsA combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA (By similarity). Has a role in growth and sporulation on acetate.
  
 0.982
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.
  
 
 0.973
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.
   
 0.969
ytcI
Putative acyl-coenzyme A synthetase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the ATP-dependent AMP-binding enzyme family.
  
 0.968
pdhC
Pyruvate dehydrogenase (dihydrolipoamide acetyltransferase E2 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).
  
 0.967
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.
