TY - JOUR A1 - Sebald, Walter A1 - Wild, G. T1 - Mitochondrial ATPase complex from Neurospora crassa N2 - The A TPase eomplex has been isolated from mitoehondria of N eurospora crassa by immunologieal teehniques. The protein ean be obtained rapidly and qua ntitatively in high purity by miero- or large-seale immunopreeipitation. Immunopreeipitation has been applied to labeled and doubly labeled mitoehondrial proteins in order to investigate the number and moleeular weights of subunit polypeptides , the site of synthesis of subunit polypeptides, and the dieycIohexyIcarbodiimide-binding protein . The A TPase complex obtained by large-seale immunopreeipitation has been used as starting ma terial for the isolation of hydrophobie polypeptides.

T1 - Puromycin sensitivity of ribosomal label after incorporation of \(^{14}\)C-labelled amino acids into isolated mitochondria from Neurospora crassa N2 - Radioactive amino acids were incorporated into isolated mitochondria from Neurospora crassa. Then the mitochondrial ribosomes were isolated and submitted to density gradient centrifugation. A preferential labelling of polysomes was observed. However, when the mitochondrial suspension was treated with puromycin after amino acid incorporation, no radioactivity could be detected in either the monosomes or the polysomes. The conclusion is drawn that isolated mitochondria under these conditions do not incorporate significant amounts of amino acids into proteins of their ribosomes.

A1 - Bücher, T. T1 - Incorporation in vivo of \(^{14}\)C-labelled amino acids into the proteins of mitochondrial ribosomes from Neurospora crassa sensitive to cycloheximide and insensitive to Chloramphenicol N2 - Radioactive amino acids were incorporated in vivo into N eurospora crassa cells, and the mitochondrial ribosomes were isolated. The incorporation of radioactivity into the proteins of these ribosomes was inhibited by cycloheximide, but not by chloramphenicol. It is therefore concluded that these proteins are synthesized on the cycloheximide sensitive and chloramphenicol insensitive cytoplasmic ribosomes.

T1 - Cycloheximide resistant incorporation of amino acids into a polypeptide of the cytochrome oxidase of Neurospora crassa N2 - Radioaetive leueine was ineorporated by N eurospora crassa mitoehondria in vivo in the presence of cyeloheximide. When the membrane protein of these mitochondria was ehromatographieally separated on oleyl polymethaerylie aeid resin, & nurober of fraetions were obtained whieh differ with respeet to their eontents of radioaetivity and eytoehromes. The highest speeifie radioaetivity was found in the fraction eontaining eytoehrome aa3• This fraetion proved to be a pure and enzymatically aetive cytoehrome oxidase. Its ratio of absorbanee at 280 nm (ox)/ 443 nm (red.) was 2.1. By means of sodium dodeeylsulfate gel-electrophoresis, this enzymewas separated into five polypeptides with molecular weights of 30000, 20000, 13000, 10000, and 8000. Only the polypeptide with the molecular weight 20000 displayed a high specific radioaetivity.

T1 - Inhibition of the assembly of cytochrome oxidase in Neurospora crassa by chloramphenicol N2 - Cytochrome oxidasewas prepared from Neurospora crassa by chromatography on oleyl polymethacrylic acid resin and separated into seven polypeptides by polyacrylamide gel electrophoresis in the presence of sodium dodecylsulfate. Incorporation oflabelled amino acids into the single polypeptideswas investigated after a pulse labelling in the absence and presence of chloramphenicol, and afterwashing out the inhibitor. Chloramphenicol (4 mg/ml) inhibited amino acid incorporation into all polypeptides 90-95%• while labeHing of the whole membrane protein was inhibited only 30%• Mter washing out the inhibitor and further growth of the cells. the four smaller polypeptides were highly labelled, whereas the other polypeptides showed only a. small increase in radioactivity. It is concluded that the four small-sized polypeptides of cytochrome oxidase are synthesized but not integrated into the functional enzyme under the action of chloramphenicol.
