Structure-function analysis in nuclear RNase P RNA
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-06)
Eukaryotic ribonuclease P (RNase P) enzymes require both RNA and protein subunits for activity in vivo and in vitro . We have undertaken an analysis of the complex RNA subunit of the nuclear holoenzyme in an effort to ...
Solubilization of hen brain neurotoxic esterase in dimethylsulfoxide
(Elsevier, 1985-10-15)
Neurotoxic esterase is the putative site of initiation of organophosphorus-induced neuropathy. The protein is membrane-associated and will thus require solubilization before it can be purified. Its enzymic activity was ...
Evolution of microstructure and magnetic properties in magnetron-sputtered CoCr thin films
(Elsevier, 1992-12)
The microstructure and magnetic-structure development in magnetron-sputtered Co-22at%Cr thin films deposited on amorphous substrates has been examined systematically and in detail. It has been found that the initial deposit ...
Michael addition of thiols with 4-methyleneglutamic acid: Preparation of adducts, their properties and presence in peanuts
(Elsevier, 1982-04-29)
The thioethers, S-(4-amino-2,4-dicarboxybutyl)cysteamine, S-(4-amino-2,4-dicarboxybutyl)cysteine and S-(4-amino-2,4-dicarboxybutyl)glutathione, were synthesized by a Michael addition between 4-methyleneglutamic acid and ...
Characterization of a topoisomerase-like activity at specific hypersensitive sites in the Drosophila histone gene cluster
(Elsevier, 1989-07-14)
It is well known that treatment of DNA-topoisomerase complexes with SDS induces cleavage of the DNA by trapping a reactive intermediate in which the topoisomerase is covalently linked to the terminal phosphates of the cut ...
Teratogenic action of platinum thymine blue
(Elsevier, 1982-08-23)
The teratogenic activity of the antitumor agent cisplatinum-2-thymine (platinum thymine blue) was investigated in rats. Pregnant Wistar-derived albino rats were given single ip injections of an aqueous solution of platinum ...
The effect of dietary nicotine on the allocation of assimilated food to energy metabolism and growth in fourth-instar larvae of the southern armyworm, Spodoptera eridania (Lepidoptera: Noctuidae)
(Springer-Verlag, 1992-03)
Dietary nicotine (0.5%), which is a substrate of the PSMO (polysubstrate monooxygenase) detoxification system in the southern armyworm Spodoptera eridania , has significant negative effects on the weight of food ingested, ...
EcoRI restriction endonuclease cleavage site map of bacteriophage P22 DNA
(Elsevier, 1978-01-25)
The seven EcoRI restriction endonuclease cleavage sites in bacteriophage P22 DNA have been mapped. The cleavage site map of circularly permuted P22 linear DNA is a circle. The positions of EcoRI sites in the early region ...
Optimal activity times and habitat choice of moose
(Springer-Verlag, 1981-02)
A set of concepts was presented which could be used to model an animal's activity cycle and habitat choice as an optimization process. The model was applied to moose ( Alces alces ) summer activity and its predictions were ...
Isolation of an acid protease from rabbit reticulocytes and evidence for its role in processing redox proteins during erythroid maturation
(Elsevier, 1981-06-30)
A protease which generates a soluble hemepeptide from bovine liver microsomal cytochrome has been isolated from the membrane fraction of rabbit reticulocytes. Inhibition by pepstatin and an acidic pH optimum indicate that ...
