Mercury transport and resistance.
Resistance to mercuric ions in bacteria is conferred by mercuric reductase, which reduces Hg(II) to Hg(0) in the cytoplasmic compartment. Specific mercuric ion transport systems exist to take up Hg(II) salts and deliver them to the active site of the reductase. This short review discusses the role of transport proteins in resistance and the mechanism of transfer of Hg(II) between the mercury-re...
متن کاملLife of Lubricated Machines
Seventy to eighty five percent of failures and wear problems in lubricated machines are caused by oil contamination. Contaminants shorten the life of all machines, especially those with fine finishes and clearances operating at high speeds and temperatures. Examples are rolling and sliding bearings, gears, vane and piston hydraulic pumps, Maintaining clean oil provides the benefits listed in Ta...
متن کاملMercury resistance (mer) operons in enterobacteria.
Mercury resistance is found in many genera of bacteria. Common amongst enterobacteria are transposons related to Tn21, which is both mercuric ion- and streptomycin-/spectinomycin- and sulphonamide-resistant. Other Tn21-related transposons often have different antibiotic resistances compared with Tn21, but share many non-antibiotic-resistance genes with it. In this article we discuss possible me...
متن کاملUrethral Plugs in Dogs
BACKGROUND Crystalline-matrix urethral plugs have not been previously reported in dogs. HYPOTHESIS/OBJECTIVES To report the composition of urethral plugs in dogs, describe clinical features of the disease, and identify overrepresented breeds. METHODS Retrospective case series. A Minnesota Urolith Center (MUC) record search was performed for urethral plugs in dogs submitted during a 6-year p...
متن کاملProbing Pores with Peptide Plugs
Extracellular proteins are made in the cytosol and transported out of the cell. Certain proteins travel the opposite way, from the outside to the cytosol. Most of these proteins are toxins made by bacteria and plants, but evidence is accumulating that certain growth factors can do the same. Toxins that enter the cytosol can, according to current knowledge, be roughly classified into two main gr...
