To exploit the enzymatic method for the synthesis of β-hydroxy-α-amino acids, the genes coding for the Escherichia coli l-threonine aldolase (LTA; EC 2.1.2.1) and Xanthomonus oryzae d-threonine aldolase (DTA) were cloned and overexpressed in E. coli through primer-directed polymerase chain reactions. The purified recombinant enzymes were studied with respect to kinetics, specificity, stability, additive
