Pseudouridine (Psi) is one of the most abundant RNA modifications in cellular RNAs that post-transcriptionally impact many aspects of RNA. However, the metabolic fate of modified RNA nucleotides has long been a question. A pseudouridine kinase (PsuK) and a pseudouridine monophosphate glycosylase (PsuG) in Escherichia coli were first characterized as involved in pseudouridine degradation by catalyzing the phosphorylation of pseudouridine to pseudouridine 5'-phosphate (PsiMP) and further hydrolyzing 5'-PsiMP to produce uracil and ribose 5'-phosphate. Recently, their homolog proteins in eukaryotes were also identified, which were named PUKI and PUMY in Arabidopsis. Here, we solved the crystal structures of apo-EcPsuK and its binary complex with Psi or N (1)-methyl-pseudouridine (m1Psi). The structure of EcPsuK showed a homodimer conformation assembled by its beta-thumb region. EcPsuK has an appropriate binding site with a series of hydrophilic and hydrophobic interactions for Psi. Moreover, our complex structure of EcPsuK-m1Psi suggested the binding pocket has an appropriate capacity for m1Psi. We also identified the monovalent ion-binding site and potential ATP-binding site. Our studies improved the understanding of the mechanism of Psi turnover.
