Abstract
Ribosomes and postribiosomal supernatant fluid (S-100) were isolated from Coxiella burnetii. The ribosomes functioned in polyuridylic acid-directed polyphenylalanine synthesis in the presence of S-100 from either C. burnetii or Escherichia coli. C. burnetii S-100 promoted translation with E. coli ribosomes. Antisera against E. coli elongation factor G and ribosomal proteins L7/L12 cross-reacted with rickettsial S-100 and ribosomes, respectively. Ribosomal proteins were analyzed by two-dimensional gel electrophoresis.
