ID 4.1.2.42 DE D-threonine aldolase. AN DTA. AN low specificity D-threonine aldolase. CA (1) D-threonine = acetaldehyde + glycine. CA (2) D-allo-threonine = acetaldehyde + glycine. CC -!- Activated by divalent metal cations (e.g. Co(2+), Ni(2+), Mn(2+) or CC Mg(2+)). CC -!- The reaction is reversible, which can lead to the interconversion of CC D-threonine and D-allo-threonine. CC -!- Several other D-beta-hydroxy-alpha-amino acids, such as D-beta- CC phenylserine, D-beta-hydroxy-alpha-aminovaleric acid and D-beta-3,4- CC dihydroxyphenylserine, can also act as substrate.
