Ascorbate Peroxidase from Soybean Root Nodules [PDF]

Plant Physiology, 1993
AP is involved in the destruction of harmful H202. In soybean (Glycine max [L] Merr.) root nodules, AP initiates a sequence of coupled redox reactions (ascorbate-GSH pathway) that results in peroxide scavenging (Dalton et al., 1986). The ascorbate-GSH pathway occurs in other plant tissues and has been extensively studied in chloroplasts where ...

Stress memory in seedlings of primed seed chickpea (Cicer arietinum L.) using sodium nitroprusside under cold stress

Plant Stress, 2023
Pea cultivation has been developed as a rich source of protein in many countries. The spring cultivation of chickpeas has low performance and efficiency due to the short length of the growth period and the confrontation of the reproductive period with ...

Engineering Ascorbate Peroxidase Activity into Cytochrome c Peroxidase [PDF]

Biochemistry, 2008
Cytochrome c peroxidase (CCP) and ascorbate peroxidase (APX) have very similar structures, and yet neither CCP nor APX exhibits each other's activities with respect to reducing substrates. APX has a unique substrate binding site near the heme propionates where ascorbate H-bonds with a surface Arg and one heme propionate (Sharp et al. (2003) Nat. Struct.

Triazine Probes Target Ascorbate Peroxidases in Plants [PDF]

Plant Physiology, 2019
Though they are rare in nature, anthropogenic 1,3,5-triazines have been used in herbicides as chemically stable scaffolds. Here, we show that small 1,3,5-triazines selectively target ascorbate peroxidases (APXs) in Arabidopsis (Arabidopsis thaliana), tomato (Solanum lycopersicum), rice (Oryza sativa), maize (Zea mays), liverwort (Marchantia polymorpha),

Engineering the active site of ascorbate peroxidase [PDF]

European Journal of Biochemistry, 2001
The oxidation of a number of thioethers, namely methyl phenyl sulphide (1), ethyl phenyl sulphide (2), isopropyl phenyl sulphide (3), n‐propyl phenyl sulphide (4), p‐chlorophenyl methyl sulphide (5), p‐nitrophenyl methyl sulphide (6) and methyl naphthalene sulphide (7), by recombinant pea cytosolic ascorbate peroxidase (rAPX) and a site‐directed ...

Arabidopsis APx-R Is a Plastidial Ascorbate-Independent Peroxidase Regulated by Photomorphogenesis

Antioxidants, 2021
Peroxidases are enzymes that catalyze the reduction of hydrogen peroxide, thus minimizing cell injury and modulating signaling pathways as response to this reactive oxygen species.

Microarray analysis of spring barley cultivars displaying differing sensitivity to physiological leaf spot (PLS) [PDF]

, 2015
peer-reviewedPhysiological leaf spot (PLS) is a disorder of spring barley (Hordeum vulgare L.), which has become more pronounced in recent years. The initial symptoms are small chlorotic/brown spots on the upper four leaves, which may develop into ...

Ascorbate deficient semi-dwarf asfL1 mutant of Lathyrus sativus exhibits alterations in antioxidant defense

Biologia Plantarum, 2012
An ascorbate-deficient semi-dwarf mutant asfL-1 was detected in 250 Gy γ-ray treated grass pea (Lathyrus sativus L.) cv. BioR-231. The mutant contained only 42 % of leaf and 20 % of root ascorbate content of mother control (MC).
