Utilization of urea by leaves of bromeliad Vriesea gigantea under water deficit: much more than a nitrogen source

Biologia Plantarum, 2017
Vriesea gigantea Gaudichaud is an epiphytic bromeliad with a high capacity to take up urea. In plants, urea is hydrolyzed by urease into ammonium and CO2, providing nitrogen to the plant.

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

Advanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

Phosphoenolpyruvate Carboxykinase Assayed at Physiological Concentrations of Metal Ions Has a High Affinity for CO2 [PDF]

, 2002
The effect of Mn2+/Mg2+ concentration on the activity of intact, homogeneous phosphoenolpyruvate carboxykinase (PEPCK) from leaves of the C4 grass, Guinea grass (Panicum maximum), have been investigated.

Label-free shotgun proteomics and metabolite analysis reveal a significant metabolic shift during citrus fruit development. [PDF]

, 2011
Label-free LC-MS/MS-based shot-gun proteomics was used to quantify the differential protein synthesis and metabolite profiling in order to assess metabolic changes during the development of citrus fruits.

Phosphoenolpyruvate Carboxylase of Escherichia coli

Journal of Biological Chemistry, 1972
Abstract Phosphoenolpyruvate carboxylase was purified from Escherichia coli, strain B (ATCC 11303), and its properties studied. Its amino acid composition and some of its structural properties closely resemble those of the enzyme recently purified by Smith ((1971) J. Biol. Chem. 246, 4234–4241).

Hepatic gluconeogenesis and regulatory mechanisms in lactating ruminants: A literature review

Animal Research and One Health, EarlyView.
phosphoenolpyruvate carboxy kinase, FBP1, and glucose‐6‐phosphatase are key rate‐limiting enzymes that determine the efficiency of gluconeogenesis. The main substrate for gluconeogenesis in the liver of ruminants is propionate, which provides more than 60% of the carbon source for gluconeogenesis.

Transcriptomic and phosphoproteomic profiling and metabolite analyses reveal the mechanism of NaHCO3-induced organic acid secretion in grapevine roots

BMC Plant Biology, 2019
Background Organic acid secretion is a widespread physiological response of plants to alkalinity. However, the characteristics and underlying mechanism of the alkali-induced secretion of organic acids are poorly understood.

Phosphorylation of phosphoenolpyruvate carboxykinase in plants. Studies in plants with C4 photosynthesis and Crassulacean acid metabolism and in germinating seeds [PDF]

, 1996
We have previously shown that phosphoenolpyruvate carboxykinase (PEPCK) is phosphorylated in vivo in the cotyledons of darkened cucumber seedlings and that phosphorylation is reversed by light [Walker and Leegood (1995) FEBS Lett. 362, 70–74].
