Zeaxanthin is an important dietary carotenoid but its abundance in our food is low. In order to provide a better supply of zeaxanthin in a staple crop, two different potato (Solanum tuberosum L.)… Expand
A novel type of lycopene ε-cyclase in the marine cyanobacterium Prochlorococcus marinus MED4
Chlorophyll-b-possessing cyanobacteria of the genus Prochlorococcus share the presence of high amounts of α- and β-carotenoids with green algae and higher plants. The branch point in carotenoid… Expand
The genome of the basal agaricomycete Xanthophyllomyces dendrorhous provides insights into the organization of its acetyl-CoA derived pathways and the evolution of Agaricomycotina
BackgroundXanthophyllomyces dendrorhous is a basal agaricomycete with uncertain taxonomic placement, known for its unique ability to produce astaxanthin, a carotenoid with antioxidant properties. It… Expand
Cloning of two carotenoid ketolase genes from Nostoc punctiforme for the heterologous production of canthaxanthin and astaxanthin
For the heterologous synthesis of keto-carotenoids such as astaxanthin, two carotenoid ketolase genes crtW38 and crtW148, were cloned from the cyanobacterium, Nostoc punctiforme PCC 73102 and… Expand

The biosynthesis pathway to diadinoxanthin and fucoxanthin was elucidated in Phaeodactylum tricornutum by a combined approach involving metabolite analysis identification of gene function. For the… Expand
High-light-dependent upregulation of carotenoids and their antioxidative properties in the cyanobacterium Synechocystis PCC 6803
Abstract Light-dependent carotenoid formation has been investigated in the cyanobacterium Synechocystis PCC 6803. Upon transfer of cultures from low- (35 μmol m −2 s −1 ) to high-intensity… Expand
Substrate specificity of the expressed carotenoid 3,4-desaturase from Rubrivivax gelatinosus reveals the detailed reaction sequence to spheroidene and spirilloxanthin.
Carotenoid biosynthesis in the photosynthetic bacterium Rubrivivax gelatinosus leads to the formation of hydroxyspheroidene and spirilloxanthin as the products of a branched pathway. In this study we… Expand

In purple bacteria, acyclic 1-methoxy carotenoids like spheroidene or spirilloxanthin are essential components of the photosynthetic apparatus. One of the last steps of their biosynthesis involves… Expand
A novel type of lycopene epsilon-cyclase in the marine cyanobacterium Prochlorococcus marinus MED4.
Chlorophyll- b-possessing cyanobacteria of the genus Prochlorococcus share the presence of high amounts of alpha- and beta-carotenoids with green algae and higher plants. The branch point in… Expand
