Manually annotated by BRENDA team
cultivars PI 255956, PI 535278 (Tars-046A) and cv. Wolven Pole, oxalate concentration in infected (infected with Sclerotinia sclerotiorum) stems of Wolven Pole is higher than in PI 255956 and PI535278. Inoculated stems of Wolven Pole have oxalate oxidase, the Sclerotinia sclerotorum resistent lines PI 255959 and PI 535278 not. Phaseolus coccineus is not as oxalat sensitiv as Phaseolus vulgaris. Infection of Phaseolus coccineus with Sclerotinia scerotorum increased the levels of oxalate, with the highest concentration in Woven Pole

LITERATURE
AlCl3
-
the activity of oxalate oxidase and the production of H2O2 in the root border colls is higher in Al-treated root tips relative to those of the control plants
Mn3+
-
treatment of the periodate-oxidized enzyme with ascorbate results in a substantioal decrease in absorption, forming a complex that is spectroscopically identified as a Mn3+ species. Mn3+ form has a 5fold higher specific activity than native recombinant oxalate oxidase.
Mn5+
-
titration of oxalate oxidase with sodium periodate results in nearly stoichometric oxidation of the enzyme to an intensely colored yellow complex, whose complete spectroscopic characterization lead to assignment to a superoxidized Mn5+ complex. Treatment of Mn2+ S49A oxalate oxidase generates the same yellow species as the glycosylated wild type enzyme. Mass spectra of isolated and periodate-treated oxalate oxidase are virtually identical, demonstating that no protein oxidation occurred. Peroxidate oxidation increases the specific activity about 5fold.
NH4Cl
specific activity of the wild type oxalate oxidase is lower in the presence of 1 M NaCl
