PROTEIN BEAUTY PARADE. “The picture emerging from these kinds of experiments shows several prominent players. Not surprisingly, ribosomal proteins and their ancillary components are highly abundant. The elongation factor EF-TU, responsible for mediating the entrance of the tRNA to the free site of the ribosome, was characterized as the most abundant protein in the original 1978 catalog with a copy number of ≈60,000 proteins per bacterial genome.”
