Human low-density lipoprotein (LDL) was glycated in vitro (5 days, glucose 50 mmol/l), labelled with 125I, and its binding and uptake by human monocyte-derived macrophages studied. Glycation produced lower binding and lower uptake. Competition experi

Summary Yeast mitochondrial Phe-tRNA synthetase is purified about 380-fold to homogeneity by precipitation with ammonium sulfate and chromatography on DEAE-cellulose, on two hydroxylapatite and on two AH-Sepharose 4B columns. The yield is 17%. The mo

The nucleoside composition of tRNA from highly purified yeast mitochondria shows the presence of T, ψ, hU, m1G, m2G, m22G, I and t6A whereas neither m7G, m5C, m3C, m1A, i6A and Y nor O′-methylated nucleosides (which are common in yeast cytoplasmic

Reversed phase chromatography of mitochondrial [3H] Phe-tRNA from Saccharomyces cerevisiae shows only one peak which elutes distinctly from cytoplasmic [14C] Phe-tRNA. Mitochondrial tRNAPhe from this peak hybridizes specifically with ϱ+ and a ϱ−

Proteolytic activity in yeast mitochondrial membranes and soluble fractions was studied using a labeled substrate: [ 14 C]dimethylcasein. Optimal activity for the two fractions was at pH 6 in phosphate buffer at 37°C. Activity was partially inhibite

Summary Conversion of large amounts of Saccharomyces cerevisiae cells to protoplasts is studied using various preparations extracted from Helix pomatia hepato-pancreatic juice. The most favorable yield in two hours incubations (88 per cent) is obtain
