Functional specialization of protein synthesis across species
Ribosomes have an exceptionally divergent content across living species. Among ~250 non-homologous ribosomal proteins found in nature, only ~30 are shared by all living species, while the remaining ~220 proteins are found only in a subset of species. A growing evidence suggests that variations in ribosome content reflect functional specialization of these miniature factories of protein synthesis: unique proteins enable a living cell to develop unique strategies of growth, execute complex life cycles, and rapidly adapt to environmental conditions, etc.
With this visual guide into ribosome evolution we aim to share our excitement to study these complex nature's building blocks and gain insight into functional specialization of one of the most extraordinary machineries of a living cell.
