چکیده

The synthesis of new, artificial ribonucleases containing two amino acid residues connected by an aliphatic linker has been developed. Target molecules were synthesized via a catalytic three-component Ugi reaction from aliphatic diisocyanides. Preliminary investigations proved unspecific nuclease activity of the new compounds towards single-stranded RNA and double-stranded circular DNA.

Autoradiographic Studies of the Effects of Antibiotics, Amino Acid Analogs, and Nucleases on the Synthesis of Dna in Cultured Mammalian Cells.

Autoradiographic studies of the effects of some antibiotics, amino acid analogs, and nucleases on the synthesis of DNA have been carried out to gain information on the regulatory mechanism of DNA replication within the cell. Cultured cells of the Chinese hamster and human cancer (HeLa) were used as experimental material. Puromycin, chloramphenicol, p-fluoro-phenylalanine, and methylated tryptop...

Nucleases in the autolysis of filamentous fungi.

RNase and DNase activities were studied in seven fungi of the subdivisions Ascomycotina, Zygomycotina and Basidiomycotina during their autolysis, and extracellular and intracellular RNase and DNase were found. RNase specific activity reached higher levels than DNase specific activity in the culture liquid and mycelial extract, except in Aspergillus nidulans. Generally maximal RNase specific act...

RNase and DNase activities of antiviral proteins from leaves of Bougainvillea xbuttiana.

Antiviral proteins (AVPs) purified from the leaves of Bougainvillea xbuttiana cv Mahara exhibited RNase activity against viral RNA of the tobamoviruses, Tobacco mosaic virus (TMV) and Sunnhemp rosette virus (SRV). They caused complete degradation of viral RNAs in a concentration-dependent manner. RNase activity gel assay ruled out the possibility of the presence of contaminating nucleases. AVPs...

Biochemical and immunological characterization of the extracellular nucleases of group B streptococci

Nearly all group B streptococcal strains representing the five major serotypes were found to produce extracellular nucleases by screening with an agar-well-diffusion technique in DNA-methyl green agar plates. Three different nucleases have been isolated and partially purified by DEAE-and carboxymethyl-cellulose chromatography. They possessed different mobilities on polyacrylamide gel electropho...

Biochemical aspects of leukemia virus-induced immunosuppression: effect of Friend disease virus on spleen nucleases and nucleic acids.

The effect of Friend disease virus infection on spleen acid nuclease activity was studied in dejtail. RNase activ ity decreased rapidly, with time, during the course of the virus-induced leukemogenesis. Within 3 to 12 days after infection there was an 80 to 90% or greater suppression of RNase activity, as calculated per mg spleen tissue or protein. RNase activity remained depressed throughout t...
