- Ribosome biogenesis is a complex, energy-requiring process where GTPases play a crucial role, especially in the maturation of bacterial, cytosolic, and mitochondrial ribosomes.
- The study focuses on Mtg3, a GTPase involved in mitochondrial ribosome small subunit development, exploring its necessary interactions and the importance of its C-terminal domain for binding.
- Findings indicate that while some mutations affect GTP binding and activity, they do not hinder Mtg3's association with mitoribosomes, suggesting a model where Mtg3 facilitates ribosome maturation without needing to hydrolyze nucleotides actively.
