Purification and characterization of ascorbate peroxidase in Chlorella vulgaris

Biochimie, 1998
Chlorella vulgaris contained only one isoform of ascorbate peroxidase (AsAP) as the hydrogen peroxide (H2O2)-scavenging system except for catalase at a specific activity of 3.3 +/- 0.2 units/mg protein. The activity of glutathione peroxidase was not detected in the extracts from cells grown in the absence and presence of sodium selenite.

Catalytic Oxidation of p-Cresol by Ascorbate Peroxidase

Archives of Biochemistry and Biophysics, 2000
Transient and steady state kinetics, together with a range of chromatographic and spectroscopic techniques, have been used to establish the mechanism and the products of the H(2)O(2)-dependent oxidation of p-cresol by ascorbate peroxidase (APX). HPLC, GC-MS, and NMR analyses are consistent with the formation of 2, 2'-dihydroxy-5,5'-dimethylbiphenyl (II)

Distribution of cytosolic ascorbate peroxidase in Angiosperms

Giornale botanico italiano, 1996
Abstract Over 80 Angiosperms have been screened for cytosolic ascorbate peroxidase by means of native-polyacrylamide gel electrophoresis techniques. The results of our analysis show that the presence of a single cytosolic ascorbate peroxidase form is the most common case in the Angiosperms investigated when seedlings or young tissues are analized.

Physiological function and regulation of ascorbate peroxidase isoforms

Journal of Experimental Botany
AbstractAscorbate peroxidase (APX) reduces H2O2 to H2O by utilizing ascorbate as a specific electron donor and constitutes the ascorbate–glutathione cycle in organelles of plants including chloroplasts, cytosol, mitochondria, and peroxisomes. It has been almost 40 years since APX was discovered as an important plant-specific H2O2-scavenging enzyme ...
