D-treoninska aldolaza (EC 4.1.2.42, D-TA, DTA, nisko specifična D-TA, nisko specifična D-treoninska aldolaza) je enzim sa sistematskim imenom D-treonin acetaldehid-lijaza (formira glicin).[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (1) D-treonin glicin + acetaldehid
- (2) D-alotreonin glicin + acetaldehid
Ovaj piridoksal-fosfatni protein aktiviraju divalentni metalni katjoni (e.g. Co2+, Ni2+, Mn2+ or Mg2+).
