ino acids. It promotes the PLP-dependent aldol condensation of glycine with a range of aromatic aldehydes. The desired products were obtained with complete stereocontrol at C(alpha) (ee>99%, D) and moderate to high selectivity at C(beta) (up to 97% de). The designed enzyme is thus similar to natural d-threonine aldolases in its substrate specificity and stereoselectivity. Moreover, its ability to utilize
