Catalase (E.C. was purified from human erythrocytes and crystallized in three different forms: orthorhombic, hexagonal and tetragonal. The structure of the orthorhombic crystal form of human erythrocyte catalase (HEC), with space group P2(1)2(1)2(1) and unit-cell parameters a = 84.9
M Eliasson et al.
Biochemical pharmacology, 58(8), 1287-1292 (1999-09-16)
The levels and subcellular distribution of enzymes involved in defenses against reactive oxygen superoxide dismutase (SOD; E.C., glutathione peroxidase (GPX; E.C., catalase (CAT; E.C., and DT-diaphorase (DT; E.C. and of the conjugating enzymes glutathione transferase (GST; E.C. and p-sulphotransferase (p-ST;
Cengiz Kaya et al.
Physiologia plantarum, 165(2), 247-263 (2018-08-10)
A study was carried out to assess the protective effects of exogenously applied nitric oxide (NO) in the form of its donor sodium nitroprusside (SNP) to strawberry seedlings (Fragaria × ananassa cv. Camarosa) grown under iron deficiency (ID), salinity stress or combination
L Guemouri et al.
Clinical chemistry, 37(11), 1932-1937 (1991-11-01)
We studied the biological variability of blood superoxide dismutase (SOD; EC, glutathione peroxidase (GPX; EC, and catalase (CAT; EC in a sample of 1836 apparently health subjects, ages 4-97 years. SOD and GPX activities were assayed in
R Halaban et al.
Proceedings of the National Academy of Sciences of the United States of America, 87(12), 4809-4813 (1990-06-01)
Melanogenesis is regulated in large part by tyrosinase (monophenol monooxygenase; monophenol, L-dopa:oxygen oxidoreductase, EC, and defective tyrosinase leads to albinism. The mechanisms for other pigmentation determinants (e.g., those operative in tyrosinase-positive albinism and in murine coat-color mutants) are not
J C Wheeler et al.
Proceedings of the National Academy of Sciences of the United States of America, 92(22), 10408-10412 (1995-10-24)
Induction of Drosophila hsp70 protein was detected during aging in flight muscle and leg muscle in the absence of heat shock, using an hsp70-specific monoclonal antibody, and in transgenic flies containing hsp70-beta-galactosidase fusion protein reporter constructs. While hsp70 and reporter
J M Bragger et al.
Biochimica et biophysica acta, 1480(1-2), 278-282 (2000-07-19)
The activities of two enzymes, beef liver catalase (EC and calf intestine alkaline phosphatase (EC, have been measured down to -97 degrees C and -100 degrees C, respectively. Enzyme activity has not previously been measured at such low
S Bensoltane et al.
Communications in agricultural and applied biological sciences, 71(3 Pt B), 1041-1048 (2007-03-30)
The present work aimed at the study of the effects of Artea and Punch; two systemic fungicides on durum Wheat (Triticum durum L. cv. GTA dur). Seeds were grown in a medium containing respectively 25, 50, 75 and 100 ppm
S Furuta et al.
Proceedings of the National Academy of Sciences of the United States of America, 83(2), 313-317 (1986-01-01)
We have isolated five cDNA clones for rat liver catalase (hydrogen peroxide:hydrogen peroxide oxidoreductase, EC These clones overlapped with each other and covered the entire length of the mRNA, which had been estimated to be 2.4 kilobases long by
Courtney B Casp et al.
Pigment cell research, 15(1), 62-66 (2002-02-12)
Vitiligo susceptibility is a complex genetic trait that may involve genes important for melanin biosynthesis, response to oxidative stress, and/or regulation of autoimmunity, as well as environmental factors. We report here case-control and family-based association studies for the catalase gene
Barbara Hawrylak-Nowak et al.
Plant physiology and biochemistry : PPB, 127, 446-456 (2018-04-25)
We examined the possibility to enhance the growth and the physiological tolerance of lamb's lettuce (Valerianella locusta L.) grown under heat stress (HS) by biofortification with selenium (Se). The plants were grown at optimal (22/19 °C; day/night) or high (35/22 °C; day/night)
R L Hanson et al.
Applied microbiology and biotechnology, 37(5), 599-603 (1992-08-01)
Biotransformations were developed to oxidize N epsilon-carbobenzoxy(CBZ)-L-lysine and to reduce the product keto acid to L-CBZ-oxylysine. Lysyl oxidase (L-lysine: O2 oxidoreductase, EC from Trichoderma viride was relatively specific for L-lysine and had very low activity with N epsilon-substituted derivatives.
Martha Sainz et al.
Physiologia plantarum, 140(1), 46-56 (2010-05-22)
Drought and heat stress have been studied extensively in plants, but most reports involve analysis of response to only one of these stresses. Studies in which both stresses were studied in combination have less commonly been reported. We report the
Márta Vitai et al.
Orvosi hetilap, 151(23), 923-931 (2010-05-25)
The pathogenic role of oxidative stress has already been proven both in energy homeostasis and bone metabolism. The effects of +22348C>T (RS769217) polymorphism of catalase (EC, hydrogenperoxid-hydrogenperoxid oxidoreduktase) gene were investigated on glucose disposal and bone mineral density in
Tibor Janda et al.
Phytochemistry, 68(12), 1674-1682 (2007-06-01)
The interaction between light and temperature during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese). Ten-day-old plants were cold hardened at 5 degrees C for 12 days under normal (250 micromol m(-2)s(-1))
