Toxicity of Hg2+ was determined in two strains of Euglena gracilis var. bacillaris: the wild-type (B) and a streptomycin-resistant strain (Smr). Cells were cultured under 12-h dark/12-h light regime or under continuous darkness. In the dark/light cul

Chromium is a highly toxic non-essential metal for microorganisms and plants. Due to its widespread industrial use, chromium (Cr) has become a serious pollutant in diverse environmental settings. The hexavalent form of the metal, Cr(VI), is considere

The flux control distribution of the net rate of state 3 respiration was determined in heart and kidney mitochondria incubated with low concentrations of pyruvate (0.5 mM) or 2-oxoglutarate (1 mM), and in conditions that led to activation of NAD-link

Intracellular distribution of Cd, cysteine, glutathione, and Cd-induced thiol peptides in Euglena gracilis cultured under photoheterotrophic conditions was studied. After 3 days of culture with 0.2 mM CdCl2, 62% of the Cd accumulated by cells was equ

The uptake and removal of mercury (added as HgCl2) from the culture medium by Euglena gracilis was studied. In cultures initiated in the light, cells accumulated a small fraction of the added heavy metal (5-13%). Mercury was both biologically and non

An important regulator of the catalytic properties of H + -ATPase is a low Mr protein, originally [1] from bovine heart mitochondria. This protein was later isolated from chloroplasts [2], bacteria [3], yeast [4,5], and liver [6,7]. Although the inhi

The importance of boundary and bulk phase phospholipids was studied on a mitochondrial ATPase complex isolated by AH-Sepharose chromatography as described by Dreyfus et al (1984, Anal. Biochem. 142,215-220), this preparation was devoid of the adenine
