Flavonoids as Inhibitors of NADP-Malic Enzyme and PEP Carboxylase from C₄Plants

Bioscience, Biotechnology, and Biochemistry, 1996
The inhibitory effects of flavonoids on the activity of two photosynthetic enzymes such as phosphoenolpyruvate carboxylase (PEPCase) and NADP-dependent malic enzyme (NADP-ME) were evaluated. The glycosylation of hydroxyl groups on the flavonoids resulted in compounds that behaved as gradually weaker inhibitors with increased size of the substituent ...

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

Experimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Biological roles of crop NADP-malic enzymes and molecular mechanisms involved in abiotic stress

, 2011
The abiotic stress tolerance of plants is very important for plant growth, development, survival and functional performance. NADP-ME is one of the most important enzymes in plants.

Dynamic Analysis of Sugar, Organic Acid, Phytohormones, and Enzyme Activities in Developing Fruit of White- and Red-Fleshed Loquat (Eriobotrya japonica Lindl.)

Horticulturae
Sweet and sour flavors are the most important indicators of loquat fruit quality; they are determined not only by variety but also by the flesh type and the concentration and change patterns of sugars, organic acids, related enzyme activities, and ...

Adaptive changes in enzyme activity and metabolic pathways in adipose tissue from meal-fed rats

Journal of Lipid Research, 1966
A number of metabolic factors and the activity of a number of enzymes were determined in meal-fed (animals fed a single daily 2 hr meal) and nibbling (ad libitum-fed) rats.

Tyrosyl Residue at or Near the Active Site of Maize NADP-malic Enzyme

Photosynthetica, 1999
Incubation of maize NADP-malic enzyme with tetranitromethane (TNM) resulted in a total loss of enzyme activity. The loss of enzyme activity was not observed at pH 6.3 but at pH 8.0. NADP-malic enzyme was inactivated to almost 90 % by incubation with an 80-fold molar excess of TNM for 5 min at 30 °C. The substrate malate or Mg2+ alone gave no protection,

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Maternal protein restriction programs the ageing kidney: Proteomic signatures of early‐life origin renal and metabolic dysfunction

The Journal of Physiology, EarlyView.
Abstract figure legend Maternal protein restriction (MPR) induced persistent renal histopathological alterations accompanied by elevated serum creatinine levels. Nephron‐segment proteomic analysis revealed region‐specific molecular dysregulation affecting Bowman's capsule (PARK7, oxidative stress sensor; MSN, cytoskeletal organization), the proximal ...

Inactivation of maize NADP-malic enzyme by Cu2+-ascorbate.

Indian journal of biochemistry & biophysics, 2012
Maize malic enzyme was rapidly inactivated by micromolar concentrations of cupric nitrate in the presence of ascorbate at pH, 5.0. Ascorbate or Cu2+ alone had no effect on enzyme activity. The substrate L-malate or NADP individually provided almost total protection against Cu2+-ascorbate inactivation.
