D-threonine aldolase (EC 4.1.2.42, D-TA, DTA, low specificity D-TA, low specificity D-threonine aldolase) is an enzyme with systematic name D-threonine acetaldehyde-lyase (glycine-forming).[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- (1) D-threonine glycine + acetaldehyde
- (2) D-allothreonine glycine + acetaldehyde
This pyridoxal-phosphate protein is activated by divalent metal cations (e.g. Co2+, Ni2+, Mn2+ or Mg2+).
