Pseudouridine 5'-phosphate (PURIDP) is a potential intermediate in RNA degradation. Pseudouridine 5'-phosphatase (HDHD1) is a Mg2+-dependent enzyme present in erythrocytes that can dephosphorylate PURIDP to pseudouridine (PURID), the fifth-most abundant nucleoside in RNA. PURID is not metabolised in mammals but excreted intact in urine (Preumont et al. 2010).
