How many host proteins do mitochondria-related organelles (MROs), which lack a genome, import? Not many. Here is a super cool paper that uses spatial proteomics to show that the MRO of an oxymonad has only 31 proteins in it! They all seem to be involved in providing small C compounds to the cytosol. (No Fe-S synthesis!) Cool stuff from Vladimír Hampl and colleagues.
