    Pathwayi: glycolysis

    This protein is involved in step 3 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.UniRule annotation
    Proteins known to be involved in the 5 steps of the subpathway in this organism are:
    1. Putative glyceraldehyde-3-phosphate dehydrogenase C (gapC), Glyceraldehyde-3-phosphate dehydrogenase A (gapA)
    2. Phosphoglycerate kinase (pgk)
    3. Probable phosphoglycerate mutase GpmB (gpmB), 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (gpmI)
    4. Enolase (eno)
    5. Pyruvate kinase I (pykF), Pyruvate kinase II (pykA)
    This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
