ENZYME entry: EC 1.17.2.1
| Accepted Name |
|---|
| Nicotinate dehydrogenase (cytochrome).
|
| Alternative Name(s) |
|---|
| Nicotinate hydroxylase. |
| Nicotinic acid hydroxylase. |
| Reaction catalysed |
|---|
| Nicotinate + a ferricytochrome + H(2)O <=> 6-hydroxynicotinate + a ferrocytochrome + 2 H(+) |
| Cofactor(s) |
|---|
| Iron-sulfur; Molybdopterin cytosine dinucleotide.
|
| Comment(s) |
|---|
- This two-component enzyme from Pseudomonas belongs to the family of
xanthine dehydrogenases, but differs from most other members of this
family.
- While most members contain an FAD cofactor, the large subunit of this
enzyme contains three c-type cytochromes, enabling it to interact
with the electron transfer chain, probably by delivering the
electrons to a cytochrome oxidase.
