Organization of mitochondrial UDP-glucose:dolichylmonophosphate glucosyltransferase in the outer membrane.

Toxicity mechanisms of Cigarette Smoke on Eye and Kidney using Isolated Mitochondria

Cigarette smoking is one of the main risk factors for premature human death associated to a variety of respiratory and vascular diseases, and cancer due to containing Hundreds of toxicants. Rat mitochondria were obtained by differential ultracentrifugation and incubated with different concentrations (1, 10 and 100%) of standardized cigarette smoke extract (CSE). Our results showed that cigarett...

A COMPARATIW STUDY ON THE BINDING OF HEXOKINASE TO THE OUTER MITOCHONDRIAL MEMBRANE AND A HYDROPHOBIC MATRIX

Biosynthetic elongation of isolated teichuronic acid polymers via glucosyl- and N-acetylmannosaminuronosyltransferases from solubilized cytoplasmic membrane fragments of Micrococcus luteus.

Cytoplasmic membrane fragments of Micrococcus luteus catalyze in vitro biosynthesis of teichuronic acid from uridine diphosphate D-glucose (UDP-glucose), uridine diphosphate N-acetyl-D-mannosaminuronic acid (UDP-ManNAcA), and uridine diphosphate N-acetyl-D-glucosamine. Membrane fragments solubilized with Thesit (dodecyl alcohol polyoxyethylene ether) can utilize UDP-glucose and UDP-ManNAcA to e...

Mitochondrial Toxicity of Depleted Uranium: Protection by Beta-Glucan

Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...
