International audience; AIR12 (Auxin Induced in Root culture) is a single gene of Arabidopsis that codes for a mono-heme cytochrome b. Recombinant AIR12 from Arabidopsis accepted electrons from ascorbate or superoxide, and donated electrons to either

Identification of an ascorbate-dependent cytochrome�b of the tonoplast membrane sharing biochemical features with members of the cytochrome�b561 family

Autor: Sandra Scagliarini, Valeria Preger, Paolo Pupillo, Paolo Trost

Publikováno v: Planta. 220:365-375

Two membrane-bound, ascorbate-dependent b-type cytochromes were identified in etiolated bean (Phaseolus vulgaris L.) hypocotyls. Following solubilization of microsomal membranes and anion-exchange chromatography at pH 8.0, two major cytochrome peaks

Ascorbate-independent electron transfer between cytochromeb 561 and a 27 kDa ascorbate peroxidase of bean hypocotyls

Autor: A. Pesaresi, Valeria Preger, Paolo Trost, Paolo Pupillo

Publikováno v: Protoplasma. 217:137-145

Cytochrome b561 (cyt b561) is a trans-membrane cytochrome probably ubiquitous in plant cells. In vitro, it is readily reduced by ascorbate or by juglonol, which in plasma membrane (PM) preparations from plant tissues is efficiently produced by a PM-a

Dissecting the Diphenylene Iodonium-Sensitive NAD(P)H:Quinone Oxidoreductase of Zucchini Plasma Membrane

Autor: Lucia Vitale, Paolo Trost, Patrizia Bonora, Paolo Pupillo, Silvia Foscarini, Valeria Preger

Publikováno v: Plant Physiology. 114:737-746

Quinone oxidoreductase activities dependent on pyridine nucleotides are associated with the plasma membrane (PM) in zucchini (Cucurbita pepo L.) hypocotyls. In the presence of NADPH, lipophilic ubiquinone homologs with up to three isoprenoid units we

**Arabidopsis thaliana** sequence analysis confirms the presence of cyt b-561 in plants: evidence for a novel protein family

Autor: Jurgen Del Favero, Francesca Sparla, Manuel Pérez-Alonso, Wim Verelst, Paolo Trost, Javier Terol-Alcayde, Han Asard, Valeria Preger

Publikováno v: Plant physiology and biochemistry

Recent advances in the Arabidopsis sequencing project has elucidated the presence of two genes Atb561-A and Atb561-B that show limited homology to the DNA sequence encoding for the mammalian chromaffin granule cytochrome b-561 (cyt b-561). Detailed a

Characterization of a novel NADH-specific, FAD-containing, soluble reductase with ferric citrate reductase activity from maize seedlings

Autor: Francesca Sparla, Paolo Trost, Valeria Preger, Paolo Pupillo

Publikováno v: Archives of biochemistry and biophysics. 363(2)

A novel NADH-dependent, soluble flavoreductase of 60 kDa, active toward ferric chelates and quinones, has been purified from maize seedlings. Two closely related isoforms were separated. The two isoforms are similar in several biochemical features, w

Publikováno v: Plasma Membrane Redox Systems and their Role in Biological Stress and Disease ISBN: 9789048151349

b-Type cytochromes (cyts) are a class of redox proteins well known from electron-transport chains found in mitochondria, chloroplasts and bacterial cell membranes. Their physiological function is dependent on the oxidation-reduction properties of the
