A procedure to prepare microsomes from the mussel digestive gland is proposed. The data concerning the biochemical characterization of this subcellular fraction shows a typical RNA:protein ratio, but the presence of hydrolytic enzymes was also found; therefore a mixture of hydrolase inhibitors to study the different biochemical characteristics was used. The biochemical data demonstrate that glucose-6-phosphatase activity (G6Pase), a typical microsomal marker in mammalian cells, is not present in mussel digestive gland microsomes but a high non-specific phosphatase activity was detected. Benzo[a]pyrene hydroxylase activity was found to be present although in a minimal amount. The evaluation of the molecular weight of the rRNA demonstrates that the larger ribosomal subunit contains RNA of Mr 1.40 X 10(-6) (approximately 26S) and the smaller subunit is composed of RNA of Mr 0.65 X 10(-6) (18S). The data from mussel digestive gland microsomes was compared with that experimentally obtained from rat liver microsomes and discussed from a functional or an evolutionary point of view.
