Abstract:
Two proteins with molecular mass 65 kDa, a heat shock protein, and an S1-like protein were found in a 30S ribosomal subunit from Mycobacterium bovis BCG. The 17-kDa protein in the 30S subunit was homologous to alpha-crystallin heat shock protein, and the 16-kDa protein in the 50S subunit was homologous to the L7/L12 protein. The latter provoked a strong delayed-type hypersensitivity reaction in the sensitized guinea pigs. The GroES-like protein (12 kDa) loosely associated with ribosomes.
