in this study, extracts and essential oils of black and red pepper and thyme were tested for antibacterial activity against escherichia coli o157:h7 andstaphylococcus aureus. black and red pepper and thyme were provided from iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. after 24 h, the crude extract was separated as an alcoholic extract and con...

A study was undertaken to determine the subcellular location of DNase-I, a major acid deoxyribonuclease in Drosophila melanogaster. Embryonic tissue used in these experiments was derived from a wild type strain and from a strain homozygous at the DNase-l locus (3-61.8) for the null activity allele, DNase-lnl24. The majority of total acid DNase and DNase-l activity is found in the small particul...

The cornified layer, the stratum corneum, of the epidermis is an efficient barrier to the passage of genetic material, i.e. nucleic acids. It contains enzymes that degrade RNA and DNA which originate from either the living part of the epidermis or from infectious agents of the environment. However, the molecular identities of these nucleases are only incompletely known at present. Here we perfo...

The DNase test is a simple, economical method that has traditionally been used as a supplemental test to identify pathogenic Staphylococcus. This test also aids in the differentiation of closely-related genera within the Klebsiella-Enterobacter-Serratia division of Enterobacteriaceae and several other pathogens, including screening of C. diphtheriae. Currently DNase activity of microorganisms w...

During chloroplast development in Euglena, the activity of a specific DNase, Euglena alkaline DNase, increases in a manner similar to that of chlorophyll synthesis, but without the lag customarily associated with the early hours of chlorophyll synthesis. The increase in Euglena alkaline DNase activity is not inhibited by chloramphenicol or by streptomycin, but is inhibited by cycloheximide. Eug...

Nucleosomes are the dominant autoantigens in patients with systemic lupus erythematosus (SLE), and immune complexes involving nucleosomes are the major cause of tissue damage. The activity of DNase I, the enzyme responsible for nucleosome degradation, has been found to be decreased in patients with SLE. However, it is not known whether DNase activity is a clinically useful parameter. The aim of...

The cytotoxicity of the bacterial toxin colicin E9 is due to a non-specific DNase that penetrates the cytoplasm of the infected organism and causes cell death. We report the first enzymological characterization of the overexpressed and purified 15 kDa DNase domain (E9 DNase) from this class of toxin. CD spectroscopy shows the E9 DNase to be structured in solution, and analytical ultracentrifuga...

After incubation with DNA human lymphocytes release neutral and acid DNase activities into the culture medium; the release depends on DNA concentration and time of cultivation. The electrophoretic mobility of the released neutral DNase activity is in accordance with DNase I and the electrophoretic mobility of the released acid DNase activity with DNase II. The released DNase activities do not o...
