sequential formation of opticallyactive intermediates with unknown stereochemistry: (−)-5-hydroxyisourate (HIU) and (−)-2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU). In accordance with the observation that a defect in HIU hydrolase causes hepatocarcinoma in mouse, a detoxification role has been proposed for the enzymes accelerating the conversion of HIU and OHCU into opticallyactive (+)-allantoin
