Abstract
The amino acid sequences of an L7/L12-type ribosomal protein (RA) from a photosynthetic bacterium, Rhodopseudomonas spheroides, was determined by manual sequencing of tyrptic, staphylococcal protease and chymotryptic peptides of the protein. The sequence of the amino-termina 50 residues was confirmed by automated Edman degradation of the intact protein in a sequenator. When compared with 1.7/L12-type proteins from other bacteria, the carboxy-termina half of the molecule is highly conserved. The amino-terminal region, however, appears to be less conserved. The presence of tyrosine residue in this protein is the first to be reported for an L7/L12-type acidic ribosomal protein from eubacteria.
