Organism
Schistosoma mansoni (Blood fluke)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalytic activityi

ATP + 3-phospho-D-glycerate = ADP + 3-phospho-D-glyceroyl phosphate.

Pathwayi: glycolysis

This protein is involved in step 2 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 (Smp_056970.3), Glyceraldehyde-3-phosphate dehydrogenase, Glyceraldehyde-3-phosphate dehydrogenase (Smp_056970.1), Glyceraldehyde-3-phosphate dehydrogenase (Smp_056970.4), Glyceraldehyde-3-phosphate dehydrogenase (Smp_056970.2)
  2. Phosphoglycerate kinase (Smp_018890), Phosphoglycerate kinase (PGK), Phosphoglycerate kinase (Smp_187370)
  3. no protein annotated in this organism
  4. Enolase (ENO)
  5. Pyruvate kinase (Smp_065610.1), Pyruvate kinase (Smp_065610.2), Pyruvate kinase (Smp_156360)
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.
