The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Hyperphenylalaninemia and serotonin deficiency in Dnajc12-deficient mice

open access: yesCommunications Biology
Serotonin exerts numerous neurological and physiological actions in the brain and in the periphery. It is generated by two different tryptophan hydroxylase enzymes, TPH1 and TPH2, in the periphery and in the brain, respectively, which are members of the ...

Two Indel Variations in the Regulated Carotenoid Pigment Gene Hold the Key to the Interspecies Flower Colour Differentiation in Liriodendron Plants

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Flower colour variation is pivotal for plant evolution, ecological adaptation, and pollinator attraction. In the Liriodendron genus, L. tulipifera features a distinct orange petal stripe which is absent in L. chinense, driven by differential carotenoid accumulation, yet the underlying genetic mechanism remains unclear.

High Protein Diet and Phenylalanine Hydroxylase Activities in Rats

open access: yesPteridines, 1989
The effects of a diet of 85% casein on the activities of the phenylalanine hydroxylases of rat liver and kidney have been compared. Whereas only the tetrahydrobiopterin-dependent activity of rat hepatic phenylalanine hydroxylase is significantly ...

Allosteric regulation of phenylalanine hydroxylase [PDF]

open access: yesArchives of Biochemistry and Biophysics, 2012
The liver enzyme phenylalanine hydroxylase is responsible for conversion of excess phenylalanine in the diet to tyrosine. Phenylalanine hydroxylase is activated by phenylalanine; this activation is inhibited by the physiological reducing substrate tetrahydrobiopterin.

Convergent Evolution and De Novo Reconstitution of Apiin Biosynthesis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Apiin, an active flavonoid apioside, occurs in phylogenetically distant plants, such as parsley and chilli pepper (Capsicum annuum L.). Its sporadic distribution suggests the existence of convergent apiin biosynthesis; however, the molecular mechanisms underlying this convergence remain unclear.

Mutation Analysis of PAH Gene in Phenylketonuria Patients from the North of Iran: Identification of Three Novel Pathogenic Variants

open access: yesInternational Journal of Preventive Medicine
Background: There are more than 1100 different pathogenic variants in the phenylalanine hydroxylase (PAH) gene that are responsible for phenylketonuria (PKU) diseases, and the spectrum of these mutations varies in different ethnic groups.

A method for phenylalanine self-monitoring using phenylalanine ammonia-lyase and a pre-existing portable ammonia detection system

open access: yesMolecular Genetics and Metabolism Reports, 2023
Phenylketonuria is an inborn error of phenylalanine metabolism caused by a phenylalanine hydroxylase deficiency. To prevent the occurrence of neurological symptoms and maternal complications resulting from phenylketonuria, patients must adhere to a ...
