Phytoene desaturase (lycopene-forming) Phytoene desaturase (lycopene-forming) Phytoene desaturase (lycopene-forming) (CrtI, "four-step phytoene desaturase") (, "15-cis-phytoene:acceptor oxidoreductase (lycopene-forming)") are enzymes found in archaea, bacteria and fungi that are involved in carotenoid biosynthesis. They catalyze the conversion of colorless 15-"cis"-phytoene into a bright red lycopene in a biochemical pathway called the poly-trans pathway. The same process in plants and cyanobacteria utilizes four separate enzymes in a poly-cis pathway. Bacterial phytoene desaturases were shown to require FAD as a cofactor for their function. During the chemical reaction in total four additional double bonds are introduced into phytoene: In 2000 it was discovered that the gene insertion
The Colour of Spring The Colour of Spring The Colour of Spring is the third studio album by English rock band Talk Talk, released in 1986. Musically, "The Colour of Spring" was a major step away from the synthesised pop of early Talk Talk, with a greater focus on guitars, pianos, and organs on such songs as "Life's What You Make It", "Living in Another World" and "Give It Up". It had a sound described by the band as much more organic than their earlier records, with the improvisation that was to dominate on their later works already apparent in the recording process. The
