Zeta-carotene isomerase

ζ-Carotene isomerase (, Z-ISO, 15-cis-zeta-carotene isomerase) is an enzyme with systematic name 9,15,9'-tricis-zeta-carotene cis-trans-isomerase. This enzyme catalyses the following chemical reaction


 * 9,15,9'-tricis-zeta-carotene $$\rightleftharpoons$$ 9,9'-dicis-zeta-carotene

This enzyme is involved in carotenoid biosynthesis.
