Beta-carotene isomerase explained

β-Carotene isomerase
Ec Number:	5.2.1.14

Beta-carotene isomerase (DWARF27 (gene)) is an enzyme with systematic name beta-carotene 9-cis-all-trans isomerase.^{[1] [2]} This enzyme catalyses the following chemical reaction

all-trans-beta-carotene

\rightleftharpoons 9-cis-beta-carotene

The enzyme participates in a pathway leading to biosynthesis of strigolactones.
