ENZYME entry: EC 3.5.99.2
| Accepted Name |
|---|
| Aminopyrimidine aminohydrolase.
|
| Alternative Name(s) |
|---|
| Thiaminase. |
| Thiaminase II. |
| Reaction catalysed |
|---|
- 4-amino-5-aminomethyl-2-methylpyrimidine + H(2)O <=> 4-amino-5-hydroxymethyl-2-methylpyrimidine + ammonia
- Thiamine + H(2)O <=> 4-amino-5-hydroxymethyl-2-methylpyrimidine + 5-(2-hydroxyethyl)-4-methylthiazole
|
| Comment(s) |
|---|
| Previously known as thiaminase II, this enzyme is involved in the
regeneration of the thiamine pyrimidine from degraded products,
rather than in thiamine degradation, and participates in thiamine
salvage pathways.
