In order to study the effect of melon powdery mildew on physiological indexes different varieties, high resistant variety ‘16-6’, medium ‘04-38’, and highly susceptible ‘15B-42’ were used as materials. The activities antioxidant defense system enzymes, contents of malondialdehyde (MDA), soluble protein chlorophyll, photosynthetic indicators in leave...

Phenylketonuria (PKU) is a metabolic disorder, in which loss of phenylalanine hydroxylase activity results in neurotoxic levels of phenylalanine. We used the Pah(enu2/enu2) PKU mouse model in short- and long-term studies of enzyme substitution therapy with PEGylated phenylalanine ammonia lyase (PEG-PAL conjugates) from 4 different species. The most therapeutically effective PAL (Av, Anabaena va...

Babesia hylomysci and B. divergens were studied for superoxide dismutase (SOD) activity by enzyme assay and isoelectric focusing (IEF). In the two Babesia species, parasite-associated SOD is cyanide-insensitive and inhibited by H2O2, indicating that iron is the cofactor metal. Measurements of SOD activity from purified parasites show that the SOD activity detected in Babesia is, for the main pa...

Abstract The objective of this work was to validate the enzymatic activity in Annona x atemoyaseeds submitted treatments with plant growth regulators belonging group gibberellins and cytokinins for overcoming dormancy during germination process. Initially, water acquisition curve determined, where two points phase II (72 144 hours) were determined evaluate superoxide dismutase (SOD), peroxidase...

background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...

In the present study, Glycyrrhiza uralensis (Leguminosae) seeds were germinated and grown with different concentrations (0, 0.05, 0.1, 0.2 and 0.4 mmol/l) of cadmium acetate, in order to investigate the effects of cadmium on the growth, uptake, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL) activities in Glycyrrhiza u...

A lytic enzyme active against viable, intact staphylococci is released into culture fluids upon lysis of bacteriophage-infected Staphylococcus aureus PS53 cells. This enzyme, staphylococcal phage-associated lysin (PAL), was partially purified by ammonium sulfate precipitation and gel filtration through Sephadex G-200. PAL is optimally active at pH 6.5 and 30 C, and lytic activity is greatly enh...

the effects of different storage temperatures and times on germination rate, malondialdehyde (mda), superoxide dismutase (sod), peroxidase (pod) and catalase (cat) activities in jatropha curcas l. seed were investigated. the results showed that germination rates of seeds stored at room temperature and 4°c for 1 month was significantly higher than those stored for 3 months at -20 and -80°c. mda ...

Enzyme substitution therapy with the phenylalanine ammonia lyase (PAL) is a new approach to the treatment of patients with phenylketonuria (PKU). This enzyme is responsible for the conversion of phenylalanine to trans-cinnamic acid. We assessed the PAL enzyme of the endemic plant Cyathobasis fruticulosa (Bunge) Aellen. for its possible role in the dietary treatment of PKU. The enzyme was found ...
