“…Conditions and treatments that stimulated cell enlargement also stimulated NADH oxidase and conditions and treatments that inhibited cell enlargement inhibited NADH oxidase. Included in the latter category were touch, [47] gravity, [48,49] decreased turgor [50] and response to auxin regulators of cell enlargement both natural, indole-3-acetic acid (IAA) and synthetic, 2,4-dichlorophenoxyacetic acid (2,4-D). [51] With plant stems, the auxins stimulate the NADH oxidase directly and promote cell enlargement.…”

ECTO-NOX (because of their cell surface location) proteins comprise a family of NAD(P)H oxidases of plants and animals that exhibit both oxidative and protein disulfide isomerase-like activities. The two biochemical activities, hydroquinone [NAD(P)H] oxidation and protein disulfide--thiol interchange alternate, a property unprecedented in the biochemical literature. A tumor-associated ECTO-NOX (tNOX) is cancer-specific and drug-responsive. The constitutive ECTO-NOX (CNOX) is ubiquitous and refractory to drugs. The physiological substrate for the oxidative activity appears to be hydroquinones of the plasma membrane such as reduced coenzyme Q10. ECTO-NOX proteins are growth-related and drive cell enlargement. Also indicated are roles in aging and in neurodegenerative diseases. The regular pattern of oscillations appears to be related to alpha-helix-beta-structure transitions and serves biochemical core oscillator of the cellular biological clock. Period length is independent of temperature (temperature compensated) and synchrony is achieved through entrainment.

“…It was suggested that plasma membrane NOXs/RBOHs and H + -ATPases (a H + pump by coupling with energy of ATP hydrolysis on plasma membranes) are functionally synchronized and they work cooperatively to maintain the membrane electrical balance while mediating plant cell growth through wall relaxation [38]. Observations on maize roots indicate that the activities of plasma membrane-associated NADPH oxidase respond both to gravity and to imposed centrifugal forces [39]. In an early study, AtRHD2, a NADPH oxidase in Arabidopsis, was reported as controlling root development by making ROS that regulates plant cell expansion through the activation of Ca 2+ channels [40].…”

NADPH oxidases (NOXs), mostly known as respiratory burst oxidase homologs (RBOHs), are the key producers of reactive oxygen species (ROS) in plants. A lot of literature has addressed ROS signaling in plant development regulation and stress responses as well as on the enzyme’s structure, evolution, function, regulation and associated mechanisms, manifesting the role of NOXs/RBOHs as the vital performers and center hubs during plant growth and signaling. This review focuses on recent advances of NOXs/RBOHs on cell growth, hormone interaction, calcium signaling, abiotic stress responses, and immunity. Several primary particles, including Ca2+, CDPKs, BIK1, ROPs/RACs, CERK, FER, ANX, SnRK and SIK1-mediated regulatory mechanisms, are fully summarized to illustrate the signaling behavior of NOXs/RBOHs and their sophisticated and dexterous crosstalks. Diverse expression and activation regulation models endow NOXs/RBOHs powerful and versatile functions in plants to maintain innate immune homeostasis and development integrity. NOXs/RBOHs and their related regulatory items are the ideal targets for crop improvement in both yield and quality during agricultural practices.

The oxygen present in dough could be used by endogenous NADH oxidase (Bacon and Morre 2001;Heckman et al 2002) to rapidly oxidize free (extractable) NAD(P)H to NAD(P) + . During such oxidation, hydrogen peroxide is formed.…”

Effect of the Coenzymes NAD(P)(H) in Straight‐Dough Breadmaking on Protein Properties and Loaf Volume

et al. 2010

Cereal Chem. 87(5):420-427The nicotinamide adenine dinucleotide coenzymes [NAD(P)(H)] are strong redox agents naturally present in wheat flour, and are indispensable cofactors in many redox reactions. Hence, it is not inconceivable that they affect gluten cross-linking during breadmaking. We investigated the effect of increasing concentrations of NAD(P)(H) on gluten cross-linking, dough properties, and bread volume using two flours of different breadmaking quality. Separate addition of the four nicotinamide coenzymes did not significantly affect mixograph properties. While addition of NAD + hardly affected bread volume, supplementation with NADP(H) and NADH significantly decreased loaf volumes of breads made using flour of high breadmaking quality. Wheat flour incubation with NAD(P)H under anaerobic conditions increased wheat flour thiol content, while NAD(P) + increased the extractability in SDS-containing medium of the protein of the strong breadmaking flour. Based on the results, it was hypothesized that at least three reactions, competing for NAD(P)(H), occur during breadmaking that determine the final effect on protein, dough, and loaf properties. Next to coenzyme hydrolysis, the experiments pointed to coenzyme oxidation and NAD(P)(H) dependent redox reactions affecting protein properties.
