The Decisive Step in Betaxanthin Biosynthesis Is a Spontaneous Reaction1 [PDF]
Plant Physiology, 1999 Abstract Experiments were performed to confirm that the aldimine bond formation is a spontaneous reaction, because attempts to find an enzyme catalyzing the last decisive step in betaxanthin biosynthesis, the aldimine formation, failed. Feeding different amino acids to betalain-forming hairy root cultures of yellow beet (Beta vulgaris L.

Frontiers in Sustainable Food Systems, 2021 Betalains are tyrosine-derived plant pigments present in several species of the Caryophyllales order. Betalains are classified in red betacyanins and yellow betaxanthins and are implicated in plant stress tolerance and visual attraction for pollinators ...

Biological Properties and Applications of Betalains
Molecules, 2021 Betalains are water-soluble pigments present in vacuoles of plants of the order Caryophyllales and in mushrooms of the genera Amanita, Hygrocybe and Hygrophorus. Betalamic acid is a constituent of all betalains.

Establishing heterologous betaxanthin pigment biosynthesis in cyanobacteria [PDF]
Metabolic EngineeringBetalains are water-soluble pigments with two major classes: red-violet betacyanins and yellow-orange betaxanthins. These pigments are increasingly being sought after as natural replacements for synthetic pigments in the food industry. Traditionally, betalains are extracted from cultivated plants.

Genetically encoded betaxanthin-based small-molecular fluorescent reporter for mammalian cells [PDF]
Nucleic Acids Research, 2020 Abstract We designed and engineered a dye production cassette encoding a heterologous pathway, including human tyrosine hydroxylase and Amanita muscaria 4,5-DOPA dioxygenase, for the biosynthesis of the betaxanthin family of plant and fungal pigments in mammalian cells.

Engineering Betalain Biosynthesis in Tomato for High Level Betanin Production in Fruits
Frontiers in Plant Science, 2021 Betalains are pigments found in plants of the Caryophyllales order, and include the red-purple betacyanins and the yellow-orange betaxanthins. The red pigment from red beets, betanin, is made from tyrosine by a biosynthetic pathway that consists of a ...
