Proteins found in the venom of E. tuberculatum with unknown function in the venoms of Hymenoptera.

ProteinSpotAction Mechanism

Medium-chain specific acyl-CoA dehydrogenase, mitochondrial-like (E. C. 1.3.99.3)60Enzyme that acts on the β-oxidation of fatty acids in mitochondria.
Aconitate hydratase mitochondrial (E.C. 4.2.1.3)3, 51 and 52 (isoforms)Catalyzes the isomerization of citrate in isocitrate in the citric acid cycle. Some studies have revealed the presence of this protein in the venoms of several arthropods, such as Vespidae Vespula maculifrons, Sicariidae Loxosceles reclusa spider, A. mellifera, among others, as well as in the cuticle of Hemiptera Coccidae Ericeruspela [7, 8].
ATP Synthase (E.C. 3.6.3.14)32ATP-forming enzyme complex from ADP and inorganic phosphate during oxidative phosphorylation in respiration and photosynthesis processes.
Citrate Synthase (E.C. 2.3.3.1)29, 30 and 34Participates in the first step of the citric acid cycle by catalyzing the condensation reaction of an acetate residue containing two carbons of an acetyl coenzyme A with an oxaloacetate molecule containing four carbons to form a six-carbon citrate.
Fructose-bisphosphate aldolase (E.C. 4.1.2.13)20, 58, 75 and 78Involved in carbohydrate metabolism, and responsible for the cleavage of fructose 1,6-bisphosphate in two trioses: glyceraldehyde 3-phosphate and dihydroxyacetone phosphate in glycolysis.
Glyceraldehyde-3-phosphate dehydrogenase (E.C. 1.2.1.12 ),16, 17, 18 and 69Participates in glucose metabolism by the Embden-Meyerhof route, catalyzing the conversion of glyceraldehyde 3-phosphate to 1,3-diphosphoglycerate.
Isocitrate dehydrogenase (E.C. 1.1.1.42)70Enzyme that catalyzes oxidative decarboxylation of isocitrate to form α-ketoglutarate in the citric acid cycle.
Nucleoside diphosphate kinase
(E.C. 2.7.4.6)
2Participates in nucleotide biosynthesis, catalyzing the conversion of the nucleoside diphosphate into nucleoside trisphosphate.
Phosphoglycerate mutase 2-like (E.C. 5.4.2.11)12Glycolytic enzyme which catalyzes the conversion of 3-phosphoglycerate to 2-phosphoglycerate
Succinyl-CoA ligase (E.C. 6.2.1.5)19, 26 and 57Enzyme that participates in the citric acid cycle, catalyzing the conversion of succinyl-CoA to succinate.
4-Hydroxybutyrate coenzyme A transferase (E.C. 2.8.3.9)35Enzyme that participates in the metabolic process involving acetyl Co-A, exhibiting transferase activity. It is well studied in bacteria and participates in the fermentation process.
