Descrição geral
Norvaline is a non-proteinogenic α-amino acid and is also called DL-α-aminovaleric acid. It is produced in Gram-negative microorganisms including Escherichia coli and is also a part of the antifungal peptide produced by Bacillus subtilis.
Aplicação
DL-Norvaline has been used as an internal standard:
- to analyze metabolites in cultured mammalian cells by gas chromatography-mass spectrometry (GC-MS)
- to convert cysteine and cystine to Cys MPA (S-2-carboxyethylthio-L-cysteine) and quantify the same using a high-performance liquid chromatography (HPLC) analyzer
- for free amino acid analysis in samples of oocytes by liquid chromatography
Ações bioquímicas/fisiológicas
DL-Norvaline is a neurotransmitter.
Norvaline mediates physiological and pathophysiological processes promoting nitric oxide production. It is used to treat Alzheimer′s disease and is effective against artificial metabolic syndrome in rats. Norvaline exhibits phase transition upon cooling below 190 K and hence it is useful in molecular machines. DL-Norvaline serves as a prototype for research in polymorphism and molecular dynamics of aliphatic α-amino acids containing linear side-chain. It influences the activity, stability, and side-chain packaging of proteins.

dl-Norvaline is a molecular crystal at room temperature and it undergoes a phase transition when cooled below 190 K. This phase transition is believed to be Martensitic, thus making it of particular interest for molecular machines. In this paper we

Oxidation-reduction (redox) reactions are ubiquitous in biology and typically occur in specific subcellular compartments. In cells, the electron transfer between molecules and organelles is commonly facilitated by pyridine nucleotides such as nicotinamide adenine dinucleotide phosphate (NADPH) and nicotinamide adenine dinucleotide

The aim of the present study was to determine whether or not lipopolysaccharide from Actinobacillus actinomycetemcomitans could stimulate arginase activity in a murine macrophage cell line (RAW264.7 cells). RAW264.7 cells were treated with A. actinomycetemcomitans-lipopolysaccharide or lipopolysaccharide from Escherichia coli

The amino acid DL-norvaline undergoes two solid-solid phase transitions between room temperature and -180 °C. Single-crystal X-ray diffraction studies show that the first of these transitions, taking place around -80 °C, is completely reversible with respect to crystal quality, whereas

Mycobacterium tuberculosis ornithine carbamoyltransferase (Mtb OTC) catalyzes the sixth step in arginine biosynthesis; it produces citrulline from carbamoyl phosphate (CP) and ornithine (ORN). Here, we report the crystal structures of Mtb OTC in orthorhombic (form I) and hexagonal (form II)
