Modifying the maker: Oxygenases target ribosome biology

Area of Science:

• Molecular Biology
• Biochemistry
• Gene Expression

Background:

• Eukaryotic protein synthesis involves complex machinery with diverse modifications to proteins and RNAs.
• These modifications regulate translation factor activity, ribosome biogenesis, and function.
• Protein synthesis is a critical control point for gene expression, often deregulated in disease.

Purpose of the Study:

• To review the role of oxygenase enzymes in targeting rRNA synthesis, protein translation, and associated cellular processes.
• To highlight emerging evidence on oxidative modifications in translation.

Main Methods:

• Literature review of current research on translational modifications.
• Focus on oxygenase-catalyzed hydroxylations and demethylations.

Main Results:

• Emerging evidence indicates translation is a significant target for oxidative modifications.
• Hydroxylations and demethylations, catalyzed by oxygenases, are key modifications.
• These enzymes link nutrient availability and metabolism to cellular processes.

Conclusions:

• Oxidative modifications, particularly hydroxylations and demethylations, play a vital role in regulating eukaryotic translation.
• Oxygenase enzymes are central to these modifications, impacting cellular processes.
• Understanding these modifications is crucial given their link to disease and gene expression control.
