Investigation of the alcoholic extract of chamomile against growth and production of catalase, Dnase and haemolysin of Staphylococcus aureus (ATCC29213) were the aims of this study In this study, German chamomile was prepared from Tehran agricultural researches center. Extraction was performed by ethanol 85 (Maceration method) then solvent is removed by vacuum distillation system (concentrated ...

Among DNase I family members, only DNase gamma causes DNA fragmentation during apoptosis. However, the molecular basis for this functional feature of DNase gamma is poorly understood. Here we describe the identification of functional NLSs (nuclear localization signals) in DNase gamma and their roles in its apoptotic function. DNase gamma contains two NLSs: a classical bipartite-type NLS (NLS1) ...

After electrophoresis in DNA-containing polyacrylamide gels, two acid DNase activities can be detected in peripheral, mononuclear cells of the human blood. One of these acid DNase activities correlates with cell proliferation; its isoelectrical point is at pI 7.4. By means of this DNase activity, a quantity of less than 1% leukemic cells can be detected. The increased acid DNase activity can in...

INTRODUCTION The removal of highly viscous mucus from the airways is an important task in the treatment of chronic lung disease like in cystic fibrosis. The inhalation of recombinant human DNase- I (rhDNase-I) is used to facilitate the removal of tenacious airway secretions in different lung diseases and especially in CF. Little is known about endogenous DNase activity in the airway surface liq...

The serum of patients with many autoimmune (AI) diseases contains small fractions of antibodies possessing both DNase and RNase activities. It was shown that immunization of rabbits with DNA, RNA, DNase I and RNase leads to production of antibodies with DNase and RNase activities. It is not known whether anti-idiotypic antibodies against DNase II can possess DNase or RNase activity. Electrophor...

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...

An endo-exonuclease has been purified from cultured monkey (CV-1) cells. The enzyme which was purified to near homogeneity to be a 65 kDa monomeric protein. The single-strand DNase activity is endonucleolytic and nonprocessive, whereas the double-strand DNase activity is exonucleolytic and processive. The enzyme was also found to have RNase activity using poly-rA as substrate. The pH optimum fo...
