ENZYME entry: EC 1.3.99.39
Accepted Name |
Carotenoid phi-ring synthase.
|
Reaction catalysed |
Carotenoid beta-end group + 2 acceptor <=> carotenoid phi-end group + 2 reduced acceptor |
Comment(s) |
- The enzyme, found in green sulfur bacteria, some cyanobacteria and
some actinobacteria, introduces additional double bonds to the
carotenoid beta-end group, leading to aromatization of the ionone
ring.
- As a result, one of the methyl groups at C-1 is transferred to
position C-2.
- It is involved in the biosynthesis of carotenoids with phi-type
aromatic end groups such as chlorobactene, beta-isorenieratene,
and isorenieratene.
