Function

[TRUB_PYRFU] Could be responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs (By similarity). [RL7A_PYRFU] Multifunctional RNA-binding protein that recognizes the K-turn motif in ribosomal RNA, box H/ACA, box C/D and box C'/D' sRNAs (By similarity). [NOP10_PYRFU] Involved in ribosome biogenesis; more specifically in 18S rRNA pseudouridylation and in cleavage of pre-rRNA (By similarity).

Publication Abstract from PubMed

Box H/ACA ribonucleoprotein protein particles catalyze the majority of pseudouridylation in functional RNA. Different from stand alone pseudouridine synthases, the RNP pseudouridine synthase comprises multiple protein subunits and an RNA subunit. Previous studies showed that each subunit, regardless its location, is sensitive to the step of subunit placement at the catalytic center and potentially to the reaction status of the substrate. Here we describe the impact of chemical substitutions of target uridine on enzyme activity and structure. We found that 3-methyluridine in place of uridine inhibited its isomerization while 2'-deoxyuridine or 4-thiouridine did not. Significantly, crystal structures of an archaeal box H/ACA RNP bound with the nonreactive and the two postreactive substrate analogues showed only subtle structural changes throughout the assembly except for a conserved tyrosine and a substrate anchoring loop of Cbf5. Our results suggest a potential role of these elements and the subunit that contacts them in substrate binding and product release.
