Application

EC Number Application Comment Organism
2.4.1.276 synthesis Escherichia coli cells that express the full six carotenoid biosynthesis genes (crtE, crtB, crtI, crtY, crtZ, and crtX) of the bacterium Pantoea ananatis synthesizes zeaxanthin 3,3'-beta-D-diglucoside and 3-beta-glucosyl-3'-beta-quinovosyl zeaxanthin. The singlet oxygen-quenching activity of zeaxanthin 3,3'-beta-D-diglucoside is superior to that of zeaxanthin Pantoea ananatis
