D-threonine aldolase

 D -threonine aldolase (,  D -TA, DTA, low specificity D -TA, low specificity D -threonine aldolase) is an enzyme with systematic name  D -threonine acetaldehyde-lyase (glycine-forming). This enzyme catalyses the following chemical reaction


 * D -threonine $$\rightleftharpoons$$ glycine + acetaldehyde
 * D -allothreonine $$\rightleftharpoons$$ glycine + acetaldehyde

This pyridoxal-phosphate protein is activated by divalent metal cations (e.g. Co2+, Ni2+, Mn2+ or Mg2+).
