How is uridine different from pseudouridine?
How is uridine different from pseudouridine?
Pseudouridine, being one of them, is the C5-glycoside isomer of uridine that contains a C-C bond between C1 of the ribose sugar and C5 of uracil, rather than usual C1-N1 bond found in uridine. The C-C bond gives it more rotational freedom and conformational flexibility.
Is pseudouridine toxic?
Compromising pseudouridine catabolism leads to strong pseudouridine accumulation and increased ΨMP content. ΨMP is toxic, causing delayed germination and growth inhibition, but compromising pseudouridine catabolism does not affect the Ψ/U ratios in RNA.
Is pseudouridine natural?
5.1 Principle. Pseudouridylation is a natural modification occurring on uridine base in order to convert it into a pseudouridine (named 5-ribosyluracil, Ψ) (Fig. 3.10). Different classes of RNAs are subject to pseudouridylation, such as tRNAs, ribosomal RNAs (rRNAs), and small nuclear RNAs (snRNAs).
What changes uridine and pseudouridine?
Pseudouridine (Ψ) is formed by isomerization of uridine via breakage of the glycosidic bond, 180° base rotation and bond reformation8. Two major classes of pseudouridine synthases (PUSs) guide pseudouridylation in either an RNA-dependent, or RNA-independent manner.
What is Pseudouridine used for?
The answer to these problems came from a well-known RNA modification, pseudouridine (Ψ), which can be used to replace uridine in the IVT mRNA. It is demonstrated that Ψ can enhance RNA stability and, in the meantime, decrease anti-RNA immune response (Karikó et al., 2008).
What does Pseudouridine base pair with?
The base pairing of (a) uridine with adenosine and pseudouridine with (b) adenosine, (c) guanosine and (d, e) uridine. Ψ is found in the TΨC loop of almost all tRNAs. For most tRNAs, Ψ is also found in the D stem and/or in the anticodon stem and loop (1).

What do snoRNAs do?
Some snoRNAs play essential roles in the nucleolytic processing of rRNAs, but the majority of them function as guide RNAs in the post-transcriptional synthesis of 2′-O-methylated nucleotides and pseudouridines in rRNAs, small nuclear RNAs (snRNAs) and probably other cellular RNAs, including even mRNAs.
