ENZYME entry: EC 4.1.2.42

Accepted Name
D-threonine aldolase.
Alternative Name(s)
DTA.
Low specificity D-threonine aldolase.
Reaction catalysed
  • D-threonine <=> glycine + acetaldehyde
  • D-allothreonine <=> glycine + acetaldehyde
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • Activated by divalent metal cations (e.g. Co(2+), Ni(2+), Mn(2+) or Mg(2+)).
  • The reaction is reversible, which can lead to the interconversion of D-threonine and D-allothreonine.
  • Several other D-beta-hydroxy-alpha-amino acids, such as D-beta- phenylserine, D-beta-hydroxy-alpha-aminovaleric acid and D-beta-3,4- dihydroxyphenylserine, can also act as substrate.
