Mutants of the carotene cyclase domain of al-2 from Neurospora crassa
Phytoene synthase and carotene cyclase, two key enzymes in carotenoid biosynthesis, are encoded by two separate genes in bacteria and plants, but by...

Genomic perspective on the photobiology of Halobacterium species NRC-1, a phototrophic, phototactic, and UV-tolerant haloarchaeon
Halobacterium species display a variety of responses to light, including phototrophic growth, phototactic behavior, and photoprotective mechanisms....

Blue-light regulation of phytoene dehydrogenase (carB) gene expression in Mucor circinelloides
The carB gene, encoding the phytoene dehydrogenase of Mucor circinelloides , was isolated by heterologous hybridisation with a probe derived from the...

Isolation and functional characterisation of a novel type of carotenoid biosynthetic gene from Xanthophyllomyces dendrorhous
The red heterobasidiomycetous yeast Xanthophyllomyces dendrorhous (perfect state of Phaffia rhodozyma ) contains a novel type of carotenoid...

Production of terpenes and terpenoids
The best-studied routes of isoprenoid biosynthesis are those of vertebrates, where terpenes and terpenoids are generally produced via the mevalonate...

Carotenoids and Carotenogenesis in Anoxygenic Photosynthetic Bacteria
More than 50 genera including about 130 species of anoxygenic photosynthetic bacteria have been described. These bacteria produce around 100...

Pigment Biosynthesis: Chlorophylls, Heme, and Carotenoids
The two major pigments found in photosynthetic eukaryotic cells are the tetrapyrroles (including chlorophylls, heme, and their derivatives) and the...

The phytoene dehydrogenase gene of Phycomyces : regulation of its expression by blue light and vitamin A
By using a polymerase chain reaction based cloning strategy we isolated the gene ( carB ) encoding the enzyme phytoene dehydrogenase from Phycomyces...

Activation and analysis of crypticcrt genes for carotenoid biosynthesis fromStreptomyces griseus
Genes encoding enzymes with sequence similarity to carotenoid biosynthetic enzymes of other organisms were cloned from Streptomyces griseus JA3933 and...

Biosynthesis of Thylakoid Membrane Lipids
Plastid membranes (thylakoids as well as the two envelope membranes) contain specific polar lipids (galactolipids, sulfolipid, phospholipids),...

Functional assignment of Erwinia herbicola Eho10 carotenoid genes expressed in Escherichia coli
Erwinia herbicola is a nonphotosynthetic bacterium that is yellow pigmented due to the presence of carotenoids. When the Erwinia carotenoid...

Carotenoids in Cyanobacteria
Carotenoids in cyanobacteria have two main functions: they serve as light-harvesting pigments in photosynthesis, and they protect against...

Carotenoid biosynthesis in microorganisms and plants
The chemical structures of α- and β-carotene were elucidated about 60 years ago. Then in the middle of this century, 14C-labelling experiments...
-
Supramolecular Membrane Organization
In cyanobacteria the outer membrane, plasma membrane and thylakoid membrane represent three structurally and functionally distinct membranes. Common...

Carotenoid biosynthesis and manipulation
The carotenoids are the most widespread group of pigments in nature, with an estimated yield of some 100 million tons annually. They are present in...

Biosynthesis of carotenoids
The carotenoids that are found in the photosynthetic pigment-protein complexes of higher plants, algae and phototrophic bacteria, including...

Some Properties of Enzymes Involved in the Biosynthesis and Metabolism of 3-Hydroxy-3-Methylglutaryl-CoA in Plants
There is hardly a single process in the living plant cell that does not require the biochemical and physiological involvement of isoprenoids. It is...
