Mitochondrial ribosomes from locust thorax muscles have been identified recently in our laboratory by specific labelling of the adhering nascent peptide chains and have been isolated from mitochondria freed of contaminating cytoplasmic ribosomes [ 1 ] . Now data are presented which show that these 60 S mitochondrial ribosomes can be dissociated into subunits of 40 S and 25 S. Gel electrophoretic patterns of the proteins from these subunits are clearly different from each other and from their cytoplasmic counterparts.
