ENZYME entry: EC 4.3.1.18

PURL: https://purl.expasy.org/enzyme/EC/4.3.1.18
Accepted Name
D-serine ammonia-lyase
Alternative Name(s)
D-hydroxy amino acid dehydratase
D-serine deaminase
D-serine dehydrase
D-serine dehydratase
D-serine dehydratase (deaminating)
D-serine hydrolase
D-serine hydro-lyase (deaminating)
Reaction catalysed
D-serine = pyruvate + NH4(+)
Comment(s)
  • The enzyme cleaves a carbon-oxygen bond, releasing a water molecule (hence the enzyme's original classification as EC 4.2.1.14) 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.
  • Also acts, slowly, on D-threonine.
  • Formerly EC 4.2.1.14.
