Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

Plant Biotechnology Journal, EarlyView.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions

THE IMPORTANCE OF DIET THERAPY IN THE TREATMENT OF PHENYLKETONURIA: A CASE REPORT

Elektronički Zbornik Radova Veleučilišta u Šibeniku, 2022
Phenylketonuria is the most common inborn error of amino acid metabolism. It is caused by the impossibility of converting the essential amino acid phenylalanine into tyrosine, most often due to insufficient production or a complete lack of the enzyme ...

Phenylalanine iminoboronates as new phenylalanine hydroxylase modulators

RSC Adv., 2014
Herein we report the discovery of new modulators of human phenylalanine hydroxylase (hPAH) inspired by the structure of its substrate and regulatorl-phenylalanine.

CsYABBY1 and CsMYB114 Enhance Acquired Drought Tolerance by Mediating Flavonoid Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought priming is a critical agronomic strategy for enhancing plant drought tolerance, yet the optimal priming intensity and transcriptional regulatory mechanisms underlying subsequent drought responses in the tea plant (Camellia sinensis) remain poorly characterised.

Chronic Immune Stimulation May Cause Moderate Impairment of Phenylalanine 4-hydroxylase

Pteridines, 2011
Phenylalanine (4)-hydroxylase (PAH, E.C. 1.14.16.1) is located mainly in liver and converts amino acid phenylalanine (Phe) to tyrosine (Tyr). In 'classical' phenylketonuria (PKU), PAH activity is reduced, whereas in 'atypical' PKU biosynthesis of the ...

Mechanism of phenylalanine regulation of phenylalanine hydroxylase.

Journal of Biological Chemistry, 1990
The mechanism of phenylalanine regulation of rat liver phenylalanine hydroxylase was studied. We show that phenylalanine "activates" phenylalanine hydroxylase, converting it from an inactive to active form, by binding at a true allosteric regulatory site.

GmMYB4 Positively Regulates Isoflavone Biosynthesis via the GmMAPK6‐GmMYB4‐MBW Module in Soybean

Plant Biotechnology Journal, EarlyView.
ABSTRACT Isoflavones, a class of bioactive compounds predominantly found in leguminous plants, are largely responsible for their beneficial effects on human health. Although MYB transcription factors (TFs) are known to be crucial regulators of isoflavone biosynthesis in soybean, the precise mechanisms underlying their regulatory functions remain poorly

PAH and QDPR deficiency associated mutations in the Novosibirsk region of the Russian Federation: Correlation of mutation type with disease manifestation and severity [PDF]

Journal of Medical Biochemistry, 2014
Background: Efficient treatment of inherited hyperphenylalaninemia requires exact identification of mutations defining the trait. Such knowledge is important both for effective individual therapy and understanding of the genetic history and evolution of ...

Genome Assembly Revealed MdZAT5 Coordinates Anthocyanin Biosynthesis in Apple Fruit Peel and Flesh by Interacting With MdHY5

Plant Biotechnology Journal, EarlyView.
ABSTRACT Anthocyanins are plant pigments that contribute to fruit coloration and nutritional quality, yet the coordinated regulation of their accumulation in both peel and flesh remains elusive. Here, we present a haplotype‐resolved genome of Malus cv. ‘Royalty’, a model cultivar with consistently red peel and flesh. A zinc‐finger transcription factor,

Immune activation and inflammation in patients with cardiovascular disease are associated with elevated phenylalanine-to-tyrosine ratios

Pteridines, 2013
Higher serum neopterin concentrations and kynurenine-to-tryptophan (Kyn/Trp) ratios are associated with increased mortality in patients with coronary artery disease (CAD). Preferentially, Th1-type cytokine interferon-γ stimulates tryptophan breakdown and
