A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
3-chloro-D-alanine dehydrochlorinase.
Reaction catalysed
3-chloro-D-alanine + H(2)O <=> pyruvate + chloride + NH(3)
Pyridoxal 5'-phosphate.
  • 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
  • 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.
