Purification and Characterization of Pea Cytosolic Ascorbate Peroxidase [PDF]
Plant Physiology, 1991 The cytosolic isoform of ascorbate peroxidase was purified to homogeneity from 14-day-old pea (Pisum sativum L.) shoots. The enzyme is a homodimer with molecular weight of 57,500, composed of two subunits with molecular weight of 29,500. Spectral analysis and inhibitor studies were consistent with the presence of a heme moiety.

Molecular Oncology, EarlyView.The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Regulation and function of ascorbate peroxidase isoenzymes [PDF]
Journal of Experimental Botany, 2002 Even under optimal conditions, many metabolic processes, including the chloroplastic, mitochondrial, and plasma membrane-linked electron transport systems of higher plants, produce active oxygen species (AOS). Furthermore, the imposition of biotic and abiotic stress conditions can give rise to excess concentrations of AOS, resulting in oxidative damage

Study of content alterations of peroxidase, ascorbate peroxidase and catalase activity in two soybean cultivars (Glycine max L. merr) under water stress [PDF]
فیزیولوژی محیطی گیاهی, 2008 Different cultivars of one species activate various enzymes such as superoxide dismutase, catalase, peroxidase, glutathione reductase and ascorbate peroxidase in order to defense against the water stress.These enzymes have important role in plant defense

Advanced Science, EarlyView.The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...
