Zeaxanthin glucosyltransferase

Zeaxanthin glucosyltransferase (, crtX (gene)) is an enzyme with systematic name UDP-glucose:zeaxanthin beta-D-glucosyltransferase. This enzyme catalyses the following chemical reaction


 * 2 UDP-glucose + zeaxanthin $$\rightleftharpoons$$ 2 UDP + zeaxanthin bis(beta-D-glucoside)

The reaction proceeds in two steps with the monoglucoside as an intermediate.
