Peroxisome proliferation occurs through enlargement, elongation and division of pre-existing peroxisomes. In the Arabidopsis apem mutant, apem3, peroxisomes are dramatically enlarged and reduced in number, revealing a defect in peroxisome proliferation. The APEM3 gene was found to encode peroxisomal membrane protein 38 (PMP38). To examine the relative role(More)
A series of novel nikkomycin analogue inhibitors of the chitin synthase of fungal cell wall was synthesized and evaluated for their inhibitory activities. Among them, the compound having a phenanthrene group at the terminal amino acid was found to possess strong anti-chitin synthase activity.
We examined DNA repair activities of a mitochondrial lysate derived from Xenopus laevis oocytes. Plasmid DNA, exposed to HCl, H2O2 or UV light, was used as the substrate for the in vitro repair reaction. DNA synthesis in the lysate was stimulated 2-8-fold by such lesions, indicating the presence of excision repair activities. This repair DNA synthesis was(More)
We find in the Bi2Sr2CaCu2O8+δ system that the characteristic temperatures T ∗ χ (below which the uniform susceptibilities χab(T ) (H⊥c) and χc(T ) (H‖c) decrease) and T ∗ ρc (below which the out-of-plane resistivity ρc(T ) shows typical upturn) coincide for all doping levels. We attribute the T dependence of χ’s and ρc to the anomalous (pseudogapped)(More)
