An antibody to a 60‐kDa protein associated with membrane‐bound ribosomes (MBRP) in Staphylococcus aureus was shown to cross‐react with a 64‐kDa protein in Bacillus subtilis . Evidence is presented suggesting that this Bacillus protein is identical to a 64‐kDa protein, possibly involved in protein secretion, described by Horiuchi et al. [Proc. Natl. Acad. Sci. USA 80 (1983) 3287–3291). Both the 60‐kDa staphylococcal protein and the 64‐kDa Bacillus protein were precipitated as a complex with three other proteins when immunoprecipitated with the staphylococcal MBRP antibody.
