    Notes: Summary Fragments of DNA with function as autonomous replication sequences in yeast were cloned from Physarum polycephalum. The ars activity is located in a 1.2 kbp fragment extanding 1.5 kbp to 2.7 kbp upstream of the 5′ end of a histone H4 gene. Our recent finding that a replication origin is located at a distance less than 3 kbp of this histone gene suggests that the ars element identified coincides with a specialized replication origin and can be used to direct chromosome replication in Physarum polycephalum.

    Influence of haemodialysis and renal transplantation on trace element concentrations in children with chronic renal failure (1986)

    Notes: Abstract Whole blood levels of Cd and Pb (μg/g Hb), serum concentrations of Sr and Zn and their urinary excretion were measured in healthy, renal transplant and dialyzed children by atomic absorption spectroscopy. Furthermore, before and after dialysis the concentrations of these elements were determined in blood/serum as well as in the dialysis fluid. The predialytic concentrations of Cd, Pb and Sr in blood/serum were significantly increased compared to controls. Haemodialysis had only minor effects on whole blood Cd and Pb levels but serum Sr and Zn concentrations increased as a result of high metal levels in dialysis fluid. Children after renal transplantation showed no alterations in Pb, Sr and Zn concentrations compared to healthy children but whole blood Cd was increased. According to the renal function the Pb, Cd and Zn urinary excretion decreased in the following order: healthy, renal transplant and dialysis children. Sr urinary excretion was increased in haemodialysis and renal transplant patients. In conclusion, we found no Zn deficiency. Elevated blood levels of Cd and Pb and elevated Sr serum concentrations in paediatric patients undergoing dialysis and increased Cd whole blood levels in renal transplant children could be of clinical interest.

    Purification and Characterization of two Extracellular β-Glucosidases from Trichoderma viride ITCC 1433 (1986)

    Notes: T. viride ITCC 1433 synthesizes a two component system for the hydrolysis of cellobiose and cellooligodextrins. 80% of the total activity are solubilized during growth. The large protein (A), mol. weight 98 000 d, is glycosylated and slightly acidic (pH = 6.1). The smaller protein (B), mol. weight 70 000 d, is unglycosylated and neutral (pH = 7.2). Both proteins form a two-step system where β-glucosidase A is active at low substrate concentrations (KM = 2.3 × 10-4 M cellobiose) while β-glucosidase B covers the range of 10-fold higher cellobiose concentrations (KM = 1.8 × 10-3 M). The enzymes are fairly stable with a residual activity of 70% at 50°C after 24 h.
