This enzyme is also called orcinol hydroxylase. The components include orcinol, hydrochloric acid, and ferric chloride. Hence, this enzyme has one substrate, 2,4-dihydroxy-6-methylbenzoate, and two products, orcinol and CO. Orcinol, a natural phenolic organic compound, occurs in many species of lichens including "R. tinctoria". Orcinol is an organic compound with the formula CHCH(OH). Gyrophoric acid, a depside, and orcinol are found in lichen. Orcinol has been detected in the "toxic glue" of the ant species "Camponotus saundersi".
