title: The site of carotenogenic enzymes in chromoplasts from Narcissus pseudonarcissus L.
abstract: The membranes from the chromoplasts of Narcissus pseudonarcissus L. which are derived from the inner envelope membrane are the site of β-carotene synthesis from [1-(14)C]isopentenyl diphosphate. The enzymes involved are partly peripheral membrane proteins (prenyltransferase, phytoene synthase) and partly integral membrane proteins (cis-trans isomerase, dehydrogenase(s), cyclase(s)). Metabolic channeling is suggested.
