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.
