ENZYME entry: EC 4.5.1.2
| Accepted Name |
|---|
| 3-chloro-D-alanine dehydrochlorinase.
|
| Reaction catalysed |
|---|
| 3-chloro-D-alanine + H(2)O <=> pyruvate + chloride + NH(3) |
| Cofactor(s) |
|---|
| Pyridoxal 5'-phosphate.
|
| Comment(s) |
|---|
- The enzyme cleaves a carbon-chlorine bond, releasing a chloride and
an unstable enamine product that tautomerizes to an imine form, which
undergoes a hydrolytic deamination to form pyruvate and ammonia.
- The latter reaction, which can occur spontaneously, can also be
catalyzed by EC 3.5.99.10.
- The enzyme's activity can also result in beta-replacement reactions,
e.g. in the presence of hydrogen sulfide it can convert 3-chloro-D-
alanine into D-cysteine and chloride.
