3.5.1.54	additional information	allophanate is produced at the active site of the UC C-terminal domain and is translocated to that of the AH N-domain for subsequent reaction. Allophanate is translocated from the active site of UC C-terminal domain to that of the AH N-domain via diffusion through solvent, instead of being channeled through the dimer	?	-	?	89
