Protein

Enolase 2

Gene

ENO2

Organism
Toxoplasma gondii
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Miscellaneous

While ENO1 and ENO2 display similar K(m) values, the pure tachyzoite-specific enzyme (ENO2) has a threefold specific activity at V(max) compared with that of the bradyzoite-specific enolase (ENO1).

Catalytic activityi

2-phospho-D-glycerate = phosphoenolpyruvate + H2O.

Cofactori

Mg2+By similarityNote: Mg2+ is required for catalysis and for stabilizing the dimer.By similarity

Pathwayi: glycolysis

This protein is involved in step 4 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Glyceraldehyde-3-phosphate dehydrogenase
  2. Phosphoglycerate kinase (pgk2), Phosphoglycerate kinase (pgk1)
  3. no protein annotated in this organism
  4. Enolase 1 (ENO1), Enolase 2 (ENO2)
  5. Pyruvate kinase (pk)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate, the pathway glycolysis and in Carbohydrate degradation.
