Application	Comment	Organism
synthesis	production of rare beta-carotene-modified carotenoids possessing 2-O, 2-H or 2-glucosyl and/or 3-O, 3-H or 3-glucosyl functionalities in their beta-ionone rings using a recombinant Escherichia coli approach, involving expression of carotenoid biosynthesis genes crtE, crtB, crtI, crtY, crtZ, crtX and crtG. From the cells of the recombinant Escherichia coli, caloxanthin i.e. (beta,beta-carotene-2,3,2',3'-tetrol)-3'-beta-D-glucose, zeaxanthin i.e. (beta,beta-carotene-3,3'-diol) 3,3'-beta-D-diglucoside, and nostoxanthin i.e. (beta,beta-carotene-2,3,3'-triol) are isolated and identified. Caloxanthin 3'-beta-D-glucoside displays potent 1O2 quenching activity	Pantoea ananatis
