Quaternary structure of pigeon liver malic enzyme [PDF]

open access: yes, 1990
Pigeon liver malic enzyme (EC 1.1.1.40) has a double dimer quaternary structure. The NADP+ analogs, aminopyridine adenine dinucleotide phosphate and nicotinamide-1.N6-ethenoadenosine dinucleotide phosphate, bind to the enzyme anti-cooperatively.

Plastidial NADP-malic enzymes from grasses: Unraveling the way to the C4 specific isoforms [PDF]

open access: yesPlant Physiology and Biochemistry, 2013
Malic enzyme is present in many plant cell compartments such as plastids, cytosol and mitochondria. Particularly relevant is the plastidial isoform that participates in the C(4) cycle providing CO(2) to RuBisCO in C(4) species. This type of photosynthesis is more frequent among grasses where anatomical preconditioning would have facilitated the ...

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

open access: yesAdvanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Regulation of the expression of NADP-malic enzyme by UV-B, red and far-red light in maize seedlings

open access: yesBrazilian Journal of Medical and Biological Research, 1999
The induction of nicotinamide adenine dinucleotide phosphate-malic enzyme (NADP-ME) in etiolated maize (Zea mays) seedlings by UV-B and UV-A radiation, and different levels of photosynthetically active radiation (PAR, 400-700 nm) was investigated by ...

A role for cytosolic isocitrate dehydrogenase as a negative regulator of glucose signaling for insulin secretion in pancreatic ß-cells. [PDF]

open access: yesPLoS ONE, 2013
Cytosolic NADPH may act as one of the signals that couple glucose metabolism to insulin secretion in the pancreatic ß-cell. NADPH levels in the cytoplasm are largely controlled by the cytosolic isoforms of malic enzyme and isocitrate dehydrogenase (IDHc).

NADP+-Malic Enzyme and Organic Acid Levels in Developing Tomato Fruits [PDF]

open access: yesJournal of the American Society for Horticultural Science, 1992
Tomato (Lycopersicon esculentum Mill., cv. Ohio 7814) fruits were harvested weekly following flowering to relate changes in NADP + -malic enzyme (NADP-ME) activity and major organic acids (malate and citrate) to fruit development.

Dose‐related propofol resistance in COVID‐19 patients: Altered drug plasma levels, mechanistic insights from neuronal‐derived extracellular vesicles and miRNA analysis

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Critical care for COVID‐19 patients presents unique challenges, particularly in sedation management. Patients demonstrate notable dose‐related resistance to propofol, potentially due to complex pharmacokinetic alterations. Emerging evidence suggests that plasma extracellular vesicle‐associated miRNA represents valuable predictive ...

Effect of cadmium and glutathione on malic enzyme activity in brown shrimps (Crangon crangon) from the Gulf of Gdańsk

open access: yesOceanologia, 2011
The high level of cadmium in the abdominal muscle of the brown shrimp Crangon crangon is due to the serious pollution of the water in the Gulf of Gdansk. The inhibition of malic enzyme (ME) activity by cadmium, and in consequence the reduced formation of

Laying the Foundation for Crassulacean Acid Metabolism (CAM) Biodesign: Expression of the C4 Metabolism Cycle Genes of CAM in Arabidopsis

open access: yesFrontiers in Plant Science, 2019
Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that exploits a temporal CO2 pump with nocturnal CO2 uptake and concentration to reduce photorespiration, improve water-use efficiency (WUE), and optimize the adaptability of ...

Purification and Characterization of the NADP-Malic Enzyme fromBradyrhizobium japonicumA1017

open access: yesBioscience, Biotechnology, and Biochemistry, 1997
An NADP-malic enzyme [EC 1.1.1.40] was purified to homogeneity from Bradyrhizobium japonicum A1017, and the molecular and physiological characteristics were surveyed. The molecular mass of one subunit of the purified enzyme was evaluated to be 77,600 Da by SDS-PAGE, and the native enzyme was a tetramer in pH 7.0 and dimer in pH 8.0 conditions, showing ...
