A new mechanism helps explain differences between eukaryotic and bacterial proteomes
(PHYSorg.com Biology)

Why do distinct species have different proteins? Is there a key that allows eukaryotic cells to produce proteins involved in multicellularity that are mostly absent in prokaryotes? These are some of the questions addressed by the team of ICREA researcher Lluís Ribas, group leader of the Gene Translation lab at the Institute for Research in Biomedicine (IRB Barcelona). Their work has led to the discovery of a mechanism that allows eukaryotic cells to synthesize proteins that bacteria find hard to produce.
