Acidic ribosomal protein family of yeast Saccharomyces cerevisiae consists of four species of 13-kDa proteins and one species of 38-kDa protein. These proteins are thought to form a complex on ribosomes functioning in the translational elongation reaction, but the structural basis how to associate with one another is not known. In this communication, we show for the first time the presence of a structure equivalent to the leucine zipper on a putative alpha-helix in the 38-kDa acidic ribosomal protein, A0. Then, all the 13-kDa acidic ribosomal proteins are shown to have two periodic arrays of hydrophobic amino acid residues arranged on the opposite sides of a putative alpha-helix, which is referred to as the "bilateral hydrophobic zipper". Therefore, it is proposed that one of the 13-kDa acidic ribosomal proteins associates with 38-kDa protein A0 via the hydrophobic zipper and then the other 13-kDa proteins associate side by side via the bilateral hydrophobic zippers.
