Toward eradication of B-vitamin deficiencies : considerations for crop biofortification [PDF]

open access: yes, 2018
'Hidden hunger' involves insufficient intake of micronutrients and is estimated to affect over two billion people on a global scale. Malnutrition of vitamins and minerals is known to cause an alarming number of casualties, even in the developed world ...

Different SNP Combinations in the GCH1 Gene and Use of Labor Analgesia [PDF]

open access: yes, 2010
Background: The aim of this study was to investigate if there is an association between different SNP combinations in the guanosine triphosphate cyclohydrolase (GCH1) gene and a number of pain behavior related outcomes during labor.

Preparation of Isotope-labeled Dihydroneopterin 3'-Triphosphate with High Specific Activity

open access: yesPteridines, 1990
Isotope-labeled dihydroneopterin 3'-triphosphate with 3H at positions C-1' and C-2', respectively, has been prepared from isotope-labeled glucose as starting material. Glucose was first converted enzymatically to ribose 5-phosphate.

Sinorhizobium meliloti Flavin Secretion and Bacteria-Host Interaction: Role of the Bifunctional RibBA Protein

open access: yesMolecular Plant-Microbe Interactions, 2014
Sinorhizobium meliloti, the nitrogen-fixing bacterial symbiont of Medicago spp. and other legumes, secretes a considerable amount of riboflavin. This precursor of the cofactors flavin mononucleotide and flavin adenine dinucleotide is a bioactive molecule

Biosynthetic Enzymes of Tetrahydrolimipterin from Green Sulfur Bacterium Chlorobium Limicola

open access: yesPteridines, 1998
Based on the structure of limipterin (Cha, Pfleiderer, and Yim, Helv, Chim. Acta, 78: 600-614. 1995 the biosynthetic pathway for the newly identified pterin glycoside was investigated. It was demonstrated that tetrahydrolimipterin (H4 -limipterin) can be

Tetrahydrobiopterin Plays a Functionally Significant Role in Lipogenesis in the Oleaginous Fungus Mortierella alpina

open access: yesFrontiers in Microbiology, 2020
Tetrahydrobiopterin (BH4) is well-known as a cofactor of phenylalanine hydroxylase (PAH) and nitric oxide synthase (NOS), but its exact role in lipogenesis is unclear.

A quantitative screen for metabolic enzyme structures reveals patterns of assembly across the yeast metabolic network. [PDF]

open access: yes, 2019
Despite the proliferation of proteins that can form filaments or phase-separated condensates, it remains unclear how this behavior is distributed over biological networks. We have found that 60 of the 440 yeast metabolic enzymes robustly form structures,

Mutant human torsinA, responsible for early-onset dystonia, dominantly suppresses GTPCH expression, dopamine levels and locomotion in Drosophila melanogaster

open access: yesBiology Open, 2015
Dystonia represents the third most common movement disorder in humans with over 20 genetic loci identified. TOR1A (DYT1), the gene responsible for the most common primary hereditary dystonia, encodes torsinA, an AAA ATPase family protein.
