RESUMO

The 30S ribosomal proteins of the K-12 and B strains of Escherichia coli differ in at least one protein component. This component, which is allelic in the two strains, has been isolated from both organisms. Amino acid analyses show that the protein from strain B contains between 20 and 28 more amino acids than does the analogue protein from strain K-12.
