Unofficial Reactions:
pyruvate + (E)-4-phenylbut-3-en-2-one + H+ = (R)-phenylhexane-2,5-dione + CO2,
pyruvate + (E)-dec-3-en-2-one + H+ = (S)-3-hexanylhexane-2,5-dione + CO2,
keto-D-ribose 5-phosphate + 3-amino-3-deoxy-D-fructose 6-phosphate → 1-deoxy-1-imino-D-erythrose 4-phosphate + D-sedoheptulose 7-phosphate,
pyruvate + (E)-non-3-en-2-one + H+ = (S)-3-pentanylhexane-2,5-dione + CO2,
D-ribose 5-phosphate + D-fructose 6-phosphate → D-glycero-D-altro-octulose 8-phosphate + D-glyceraldehyde 3-phosphate,
pyruvate + 2-hydroxychalcone + H+ = 3-(2-hydroxyphenyl)-1-phenylpentane-1,4-dione + CO2,
D-ribose 5-phosphate + D-sedoheptulose 7-phosphate → D-glycero-D-altro-octulose 8-phosphate + D-erythrose 4-phosphate
