zeta-carotene desaturase has no preference for certain isomers. The nature of the isomers formed during catalysis depends strictly on the isomeric composition of the substrate. Different lycopene isomers are formed, including substantial amounts of the all-trans form, together with 7,7',9,9'-tetracis prolycopene via the corresponding neurosporene isomers
