In starved fission yeast, ribosomes adopt an unusual upside-down orientation while attaching themselves to mitochondria. This behavior, which promotes survival through the suspension of protein ...

Mitochondrial ribosomes, or mitoribosomes, are specialised organellar complexes responsible for synthesising a subset of proteins encoded by mitochondrial DNA. These proteins are critical for the ...

How a cell's mitochondria make their own protein factories Date: December 8, 2022 Source: Rockefeller University Summary: The findings shed a rare light on mitoribosomes, the unique ribosomes ...

Mitochondria are organelles that can be found in each eukaryotic cell. They are the power plants of the cell and contain their own mitochondrial ribosomes (mitoribosomes).

Proteins make life and are made by ribosomes. In mitochondria, the repertoire of the mitoribosomal architectures turns out to be much more diverse than previously thought. A paper published in ...

On top of that, mitochondrial ribosomes and tRNAs are very similar to those found in bacteria. Since the endosymbiont hypothesis came about, two scenarios - the “archezoan” and “symbiogenesis” - have ...

Ribosomes are the cell's heavyweight molecular machinery that produces proteins. It turned out, however, that in hungry yeast cells, the ribosomes that crowd on the surface of the mitochondria don ...

New work published in EMBO Reports has indicated that there are ribosomes, another kind of organelle that works to manufacture proteins, attached to mitochondria. Because of the role of ribosomes in ...

The discovery that brain ageing may be driven by jammed-up protein factories could lead to better ways to help us stay sharp ...

An international collaboration among researchers from Finland, Sweden, UK and the USA has captured ribosomes translating messenger RNA expressed from the maternally inherited mitochondrial genome.
