Summary
Ribosomal protein S1 from a newly isolated Escherichia coli mutant has a molecular weight of about 54,000 which is smaller than the wild type S1 (M.W. 65,000). The isoelectric points of the smaller and the wild type S1 species are similar in the gel electrophoresis system of O'Farrell (1975). Genetic analyses by Hfr conjugation and P1 phage transduction indicate that the mutation affecting S1 (rpsA) is located close to the serC gene [20 min on the E. coli genetic map of Bachmann et al. (1976)], with a co-transduction frequency of 61%. The most probable gene order is serC-rpsA-cmlB.
