The complete amino acid sequence of ribosomal protein L2 from the moderate thermophile Bacillus stearothermophilus has been determined. This has been achieved by the sequence analysis of peptides derived by enzymatic digestion with Staphylococcus aureus protease, trypsin and chymotrypsin, as well as by chemical cleavage with o-iodosobenzoic acid. The protein contains 275 amino acid residues and has a calculated molecular mass of 30201 Da. Comparison of this sequence with sequences of the corresponding proteins from Escherichia coli and from spinach and tobacco chloroplasts reveals that 60% of the residues of protein L2 from B. stearothermophilus are identical to those of the protein from E. coli and 45% are identical to those found in the two chloroplast proteins. There are extended regions of totally conserved sequence at positions 54-58 (GGGHK), 81-86 (EYDPNR), and 224-230 (MNPVDHP) in all four proteins.
