Lycopene ε-cyclase (EC 5.5.1.18, CrtL-e, LCYe) is an enzyme with systematic name carotenoid psi-end group lyase (decyclizing).[1][2] This enzyme catalyses the following chemical reaction
carotenoid psi-end group carotenoid epsilon-end group
The carotenoid lycopene has the psi-end group at both ends.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
