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

Bio-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

Cysteine-10 on 17 β-Hydroxysteroid dehydrogenase 1 has stabilizing interactions in the cofactor binding region and renders sensitivity to sulfhydryl modifying chemicals [PDF]

, 2013
17 β-Hydroxysteroid dehydrogenase type 1 (17 β -HSD1) catalyzes the conversion of estrone to the potent estrogen estradiol. 17 β -HSD1 is highly expressed in breast and ovary tissues and represents a prognostic marker for the tumor progression and ...

Cytosolic NADP-isocitrate dehydrogenase in Arabidopsis leaves and roots

Biologia Plantarum, 2012
NADP-dependent isocitrate dehydrogenase (NADP-ICDH) catalyses the production of NADPH, which is an essential component in the cellular homeostasis. In Arabidopsis, the kinetic parameters (K m and V max) of cytosolic NADP-ICDH were different in leaves and

Characterization of theThreshold for NAD(P)H:quinone Oxidoreductase Activity in Intact Sulforaphane-treated Pulmonary Arterial Endothelial Cells [PDF]

, 2011
Treatment of bovine pulmonary arterial endothelial cells in culture with the phase II enzyme inducer sulforaphane (5 μM, 24 h; sulf-treated) increased cell-lysate NAD(P)H:quinone oxidoreductase (NQO1) activity by 5.7 ± 0.6 (mean ± SEM)-fold, but intact ...

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]

, 1999
We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).

Phenotypic landscape inference reveals multiple evolutionary paths to C$_4$ photosynthesis [PDF]

, 2013
C$_4$ photosynthesis has independently evolved from the ancestral C$_3$ pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear.

Direct stimulation of NADP+ synthesis through Akt-mediated phosphorylation of NAD kinase

Science, 2019
Akt produces reducing power The protein kinase Akt provides a link from growth factors to the production of metabolic reducing power within the cell. Hoxhaj et al. discovered that Akt directly phosphorylates nicotinamide adenine dinucleotide kinase (NADK)

Relationships Between C4 Enzyme Activities and Yield in Soybeans (Glycine max (L.) Merr.)

Journal of Integrative Agriculture, 2013
To study the relationships between C4 enzyme activities and yield, C4 enzyme activities (phosphoenolpyruvate carboxylase (PEPCase), NADP-malate dehydrogenase (NADP-MDH), NADP-malic enzyme (NADP-ME), and pyruvate phosphate dikinase (PPDK)) in different ...
