1. The Bowen-Conradi syndrome protein Nep1 (Emg1) has a dual role in eukaryotic ribosome biogenesis, as an essential assembly factor and in the methylation of Ψ1191 in yeast 18S rRNA
Britta Meyer, Jan Philip Wurm, Peter Kötter, Matthias S Leisegang, Valeska Schilling, Markus Buchhaupt, Martin Held, Ute Bahr, Michael Karas, Alexander Heckel, Markus T Bohnsack, Jens Wöhnert, Karl-Dieter Entian. Nucleic Acids Res. 2011 Mar;39(4):1526-37. doi: 10.1093/nar/gkq931.
The Nep1 (Emg1) SPOUT-class methyltransferase is an essential ribosome assembly factor and the human Bowen-Conradi syndrome (BCS) is caused by a specific Nep1(D86G) mutation. We recently showed in vitro that Methanocaldococcus jannaschii Nep1 is a sequence-specific pseudouridine-N1-methyltransferase. Here, we show that in yeast the in vivo target site for Nep1-catalyzed methylation is located within loop 35 of the 18S rRNA that contains the unique hypermodification of U1191 to 1-methyl-3-(3-amino-3-carboxypropyl)-pseudouri-dine (m1acp3Ψ). Specific (14)C-methionine labelling of 18S rRNA in yeast mutants showed that Nep1 is not required for acp-modification but suggested a function in Ψ1191 methylation. ESI MS analysis of acp-modified Ψ-nucleosides in a Δnep1-mutant showed that Nep1 catalyzes the Ψ1191 methylation in vivo. Remarkably, the restored growth of a nep1-1(ts) mutant upon addition of S-adenosylmethionine was even observed after preventing U1191 methylation in a Δsnr35 mutant. This strongly suggests a dual Nep1 function, as Ψ1191-methyltransferase and ribosome assembly factor. Interestingly, the Nep1 methyltransferase activity is not affected upon introduction of the BCS mutation. Instead, the mutated protein shows enhanced dimerization propensity and increased affinity for its RNA-target in vitro. Furthermore, the BCS mutation prevents nucleolar accumulation of Nep1, which could be the reason for reduced growth in yeast and the Bowen-Conradi syndrome.
2. Metabolomic changes in cats with renal disease and calcium oxalate uroliths
Dennis E Jewell, Selena K Tavener, Regina L Hollar, Kiran S Panickar. Metabolomics. 2022 Aug 13;18(8):68. doi: 10.1007/s11306-022-01925-4.
There is a significant incidence of cats with renal disease (RD) and calcium oxalate (CaOx) kidney uroliths in domesticated cats. Foods which aid in the management of these diseases may be enhanced through understanding the underlying metabolomic changes. Assess the metabolomic profile with a view to identifying metabolomic targets which could aid in the management of renal disease and CaOx uroliths. This is a retrospective investigation of 42 cats: 19 healthy kidney controls, 11 with RD, and 12 that formed CaOx nephroliths. Cats were evaluated as adults (2 through 7 years) and at the end of life for plasma metabolomics, body composition, and markers of renal dysfunction. Kidney sections were assessed by Pizzolato stain at the end of life for detection of CaOx crystals. CaOx stone presence was also assessed by analysis of stones removed from the kidney at the end of life. There were 791 metabolites identified with 91 having significant (p < 0.05, q < 0.1) changes between groups. Many changes in metabolite concentrations could be explained by the loss of renal function being most acute in the cats with RD while the cats with CaOx stones were intermediate between control and RD (e.g., urea, creatinine, pseudouridine, dimethylarginines). However, the concentrations of some metabolites differentiated RD from CaOx stone forming cats. These were either increased in the RD cats (e.g., cystathionine, dodecanedioate, 3-(3-amino-3-carboxypropyl) uridine, 5-methyl-2'-deoxycytidine) or comparatively increased in the CaOx stone forming cats (phenylpyruvate, 4-hydroxyphenylpyruvate, alpha-ketobutyrate, retinal). The metabolomic changes show specific metabolites which respond generally to both renal diseases while the metabolomic profile still differentiates cats with RD and cats with CaOx uroliths.
3. Synthesis and solution conformation studies of 3-substituted uridine and pseudouridine derivatives
Yu-Cheng Chang, Jayatilake Herath, Tony H-H Wang, Christine S Chow. Bioorg Med Chem. 2008 Mar 1;16(5):2676-86. doi: 10.1016/j.bmc.2007.11.039.
A series of 3-substituted uridine and pseudouridine derivatives, based on the naturally occurring 3-(3-amino-3-carboxypropyl) modification, were synthesized. Their aqueous solution conformations were determined by using circular dichroism and NMR spectroscopy. Functional group composition and chain length were shown to have only a subtle influence on the distribution of syn/anti conformations of the modified nucleosides. The dominating factor appears to be the glycosidic linkage (C- vs. N-glycoside) in determining the nucleoside conformation.
