Lycopene;番茄红素

番茄红素lycopene

C 40 H 56 。是类胡罗卜素碳氢化合物的一种，亦称ψ，ψ - 胡罗卜素。是胡罗卜素的异构体。吸收峰在 548 、 507.5 、 477 纳米（在二硫化碳中）。番茄红素是构成番茄（ Lycopersicum esculentum ）和其他许多果实的红色素的成分，一般在叶中见不到。在番茄果实处于绿色的时期，类胡罗卜素较少，而叶绿素较多，随着果实的成熟叶绿素的急剧减少，而类胡罗卜素（主要是番茄红素、β - 胡罗卜素，也有少量其他有机化合物）则显著增加。普通的番茄红素中的双键全是稳定

Peroxisome Targeting of Lycopene Pathway Enzymes in Pichia pastoris

with a precursor pathway present in a specific cellular location because yeasts, being eukaryotes, have more defined intracellular location. Here, peroxisomal targeting of lycopene pathway enzymes, CrtE, CrtB, and CrtI, by fusing to peroxisomal targeting sequence

Bioengineering of Oleaginous Yeast Yarrowia lipolytica for Lycopene Production

-added products such as carotenoid and its derivatives have been explored. In this chapter, we describe methods to integrate genes involved in lycopene biosynthesis in Yarrowia . Each bacterial gene involved in lycopene biosynthesis, crtE , crtB
