چکیده
The effect of animal myeloperoxidase (EC 1 .I 1 .1.7) on the viability of a plant pathogen was determined. Lethality of hydrogen peroxide to germinating spores of Asoeraillus flavus increased go-fold enzymically. Singlet oxygen was present but hypochlorite accounted for two-thirds of the increase. The results indicate myeloperoxidase could improve microbial resistance in plants, perhaps transgenically.

a calcium ionophore, a phorbol ester, was studied. Upon stimulation with arachidonic acid or 7-hexachlorocyclohexane, Me$O-differentiated HL-60 cells generated superoxide (0~~) at higher rates than dbcAMP-differentiated cells. Undifferentiated cells generated 02only at low rates upon stimulation with the above agents. In cell-freesystems, NADPH oxidase activity was reconstituted by combining me...

The stoichiometric relationship between thiol oxidized and NO reduced was studied for the reaction catalyzed by nitric oxide reductase from Paracoccus denitrificans. The reaction systems consisted of dithiothreitol, ascorbate, phenazine methosulfate, enzyme and NO, or that system minus ascorbate. The mole ratio of thiol groups oxidized to NO reduced was observed to be 2.3 to 1.5 over a range of...

Background: The key enzyme of estrogen biosynthesis, aromatase cytochrome P450,is encoded by the CYP19 gene.CYP19 plays an important role in the development,function,an regulation of the female reproduction cycle. Thus, it is the potential candidate gene affecting fertility performance in human. CYP19 transcripts are expressed mainly in the ovary,testes,breast,adipose tissue and brain. Tissue e...
