Compound as reactive (1)
orsellinate + (2E,6E)-farnesyl diphosphate → grifolate + diphosphate
Compound as product (2)
3 H+ + 3 malonyl-CoA + H2O + acetyl-CoA → 3 CO2 + 4 coenzyme A + H2O + orsellinate + H+
H2O + O-orsellinate depside → 2 orsellinate + H+
Reversible reaction (1)
orsellinate + H+ ↔ orcinol + CO2
