Beta-carotene isomerase

Beta-carotene isomerase (EC 5.2.1.14, DWARF27 (gene)) is an enzyme with system 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.
