Halofunctionalization of alkenes by vanadium chloroperoxidase from Curvularia inaequalis.
The vanadium-dependent chloroperoxidase from Curvularia inaequalis is a stable and efficient biocatalyst for the hydroxyhalogenation of a broad range of alkenes into halohydrins. Up to 1 200 000 TON with 69 s-1 TOF were observed for the biocatalyst. A bienzymatic cascade to yield epoxides as reaction products is presented.
متن کاملThe stability and steady-state kinetics of vanadium chloroperoxidase from the fungus Curvularia inaequalis.
In this article we report on the steady-state kinetics of the chlorination and the stability of the vanadium chloroperoxidase from the fungus Curvularia inaequalis. The data show that the kinetics of this enzyme resemble that of the vanadium bromoperoxidase from the seaweed Ascophyllum nodosum. At low pH, chloride inhibited the enzyme, but the inhibition was of a dual nature. At pH 4.1 a mixed ...
متن کاملX-ray structure of a vanadium-containing enzyme: chloroperoxidase from the fungus Curvularia inaequalis.
The chloroperoxidase (EC 1.11.1.-) from the fungus Curvularia inaequalis belongs to a class of vanadium enzymes that oxidize halides in the presence of hydrogen peroxide to the corresponding hypohalous acids. The 2.1 A crystal structure (R = 20%) of an azide chloroperoxidase complex reveals the geometry of the catalytic vanadium center. Azide coordinates directly to the metal center, resulting ...
متن کاملPathogenicity of Alternaria Species Isolated from Chamaecyparis lawsonia In Vitro
Chamaecyparis lawsonia, which brings beauty in parks and green space, is attacked by a variety of pathogenic agents specially fungi. In this study, some Chamaecyparis lawsonia available in parks that had disease symptoms were sampled. After sample collection, in order to isolate fungal pathogens, cuts of the infected plant tissues were placed on PDA (potato dextrose agar) and later were put on...
متن کاملIdentification of some grass-associated species of Bipolaris, Curvularia and Exserohilum in selected regions of Iran
Infected tissues of roots and leaves of various grasses as well as soil around their rhizosphere were sampled from Fars, Golestan, Isfahan, Khorasan Shomali, Khorasan Razavi, Mazandaran and Semnan provinces (Iran). Based on morphological characteristics and available keys, four species of Bipolaris including B. austreliensis, B. indica, B. micropus and B. spicifera, four species of Curvularia i...
