Adaptation responses in C4 photosynthesis of sweet maize (Zea mays L.) exposed to nicosulfuron

open access: yesEcotoxicology and Environmental Safety, 2021
Nicosulfuron is an ingredient in photosynthesis-inhibiting herbicides and has been widely used in corn post-emergence weed control. In the current study, a pair of sister lines, HK301 (nicosulfuron-tolerence, NT) and HK320 (nicosulfuron-sensitive, NS ...

NADPH Dehydrogenase Gene Regulates Energy Distribution and Fatty Acid Metabolism During Fruiting Body Formation in the Filamentous Fungus Podospora anserina. [PDF]

open access: yesMicrob Biotechnol
NADPH dehydrogenase gene deletion significantly triggered NADPH/NADP+ increase in mutant strains. NADPH gene deletion promoted Fatty acid biosynthesis and repressed β‐oxidation. NADPH gene deletion decreased oxidative phosphorylation and increased substrate‐level phosphorylation. Mutants exhibited hypersensitivity to oxidative stress, but promoted more

Integrative structural and functional analysis of human malic enzyme 3: A potential therapeutic target for pancreatic cancer

open access: yesHeliyon, 2022
Malic enzymes (ME1, ME2, and ME3) are involved in cellular energy regulation, redox homeostasis, and biosynthetic processes, through the production of pyruvate and reducing agent NAD(P)H.

Photosynthetic nitrogen- and water-use efficiencies in C3 and C4 subtype grasses grown under two nitrogen supply levels

open access: yesPlant Production Science, 2021
C4 plants have higher photosynthetic nitrogen- and water-use efficiencies (PNUE and PWUE) than C3 plants. Some studies on C4 grasses have reported that NADP-malic enzyme (NADP-ME) grasses have higher PNUE than NAD-malic enzyme (NAD-ME) grasses, whereas ...

Change in Cofactor Specificity of Oxidoreductases by Adaptive Evolution of an Escherichia coli NADPH-Auxotrophic Strain

open access: yesmBio, 2021
The nicotinamide cofactor specificity of enzymes plays a key role in regulating metabolic processes and attaining cellular homeostasis. Multiple studies have used enzyme engineering tools or a directed evolution approach to switch the cofactor preference

A Comprehensive Analysis of the NADP-Malic Enzyme Gene Family of Arabidopsis [PDF]

open access: yesPlant Physiology, 2005
Abstract The Arabidopsis (Arabidopsis thaliana) genome contains four genes encoding putative NADP-malic enzymes (MEs; AtNADP-ME1–ME4). NADP-ME4 is localized to plastids, whereas the other three isoforms do not possess any predicted organellar targeting sequence and are therefore expected to be cytosolic.

The Effect of Rootstock on the Activity of Key Enzymes in Acid Metabolism and the Expression of Related Genes in ‘Cabernet Sauvignon’ Grapes

open access: yesAgronomy, 2023
The types and contents of organic acids in wine grapes determine wine quality. To explore the effects of different rootstocks on the acid metabolism of ‘Cabernet Sauvignon’ grapes, various perennial rootstock–scion combinations were used as experimental ...

Elements Required for an Efficient NADP-Malic Enzyme Type C4 Photosynthesis       [PDF]

open access: yesPlant Physiology, 2014
Abstract C4 photosynthesis has higher light, nitrogen, and water use efficiencies than C3 photosynthesis. Although the basic anatomical, cellular, and biochemical features of C4 photosynthesis are well understood, the quantitative significance of each element of C4 photosynthesis to the high photosynthetic efficiency are not well defined.

Extraction and Measurement the Activities of Cytosolic Phosphoenolpyruvate Carboxykinase (PEPCK) and Plastidic NADP-dependent Malic Enzyme (ME) on Tomato (Solanum lycopersicum)

open access: yesBio-Protocol, 2014
A recent study demonstrated that cytosolic phosphoenolpyruvate carboxykinase (PEPCK) and NADP-malic enzyme (NADP-ME) have an important role in malate metabolism during fruit ripening (Osorio et al., 2013). PEPCK catalyze the ATP-dependent decarboxylation

The Differences between NAD-ME and NADP-ME Subtypes of C4 Photosynthesis: More than Decarboxylating Enzymes

open access: yesFrontiers in Plant Science, 2016
As an adaptation to changing climatic conditions that caused high rates of photorespiration, C4 plants have evolved to display higher photosynthetic efficiency than C3 plants under elevated temperature, high light intensities, and drought.
