Prolycopene isomerase (
EC5.2.1.13, CRTISO, carotene cis-trans isomerase, ZEBRA2 (gene), carotene isomerase, carotenoid isomerase) is an
enzyme with
systematic name7,9,7',9'-tetracis-lycopene cis-trans-isomerase.[1][2][3][4] This enzyme
catalyses the following
chemical reaction
7,9,7',9'-tetracis-lycopene all-trans-lycopene
This enzyme is involved in
carotenoid biosynthesis.
