Eukaryotic RNA Polymerases

17.2K
RNA Polymerase (RNAP) is conserved in all animals, with bacterial, archaeal, and eukaryotic RNAPs sharing significant sequence, structural, and functional similarities. Among the three eukaryotic RNAPs, RNA Polymerase II is most similar to bacterial RNAP in terms of both structural organization and folding topologies of the enzyme subunits. However, these similarities are not reflected in their mechanism of action.
All three eukaryotic RNAPs require specific transcription factors, of which the...

Biosynthesis of Nucleic Acids

1.7K
Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...

Bacterial RNA Polymerase

19.9K
Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

12.3K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Pseudouridine is a common RNA modification, isomerizing uridine.
  • Pseudouridine synthases catalyze this essential post-transcriptional modification.
  • Understanding pseudouridine synthase function is key to RNA biology.

Purpose of the Study:

  • Investigate the biological significance of eukaryotic pseudouridine synthases.
  • Characterize yeast phenotypes resulting from pseudouridine synthase gene deletion.
  • Explore the broader implications of pseudouridine modification in different organisms.

Main Methods:

  • Utilized Saccharomyces cerevisiae (yeast) as a model organism.
  • Performed comprehensive statistical analysis on automated gene deletion (perturbation) growth data.
  • Applied bi-logistic curve analysis to characterize yeast growth phenotypes.

Main Results:

  • Pseudouridine synthase gene deletions resulted in altered yeast growth properties, including enhanced and biphasic growth curves.
  • Literature review revealed pseudouridine synthase roles in Toxoplasma gondii differentiation.
  • Mutations in pseudouridine synthase genes are associated with human diseases like MLASA and dyskeratosis congenita.

Conclusions:
