Vitamin B(6)-dependent enzymes may be grouped into five evolutionarily unrelated families, each having a different fold. Within fold type I enzymes, L-threonine aldolase (L-TA) and fungal alanine racemase (AlaRac) belong to a subgroup of structurally and mechanistically closely related proteins

The Y265A mutant of alanine racemase (alrY265A) was evaluated as a catalyst for the synthesis of beta-hydroxy-alpha-amino acids. It promotes the PLP-dependent aldol condensation of glycine with a range of aromatic aldehydes. The desired products were obtained with complete stereocontrol

We have isolated the gene encoding L-allo-threonine aldolase (L-allo-TA) from Aeromonas jandaei DK-39, a pyridoxal 5'-phosphate (PLP)-dependent enzyme that stereospecifically catalyzes the interconversion of L-allo-threonine and glycine. The gene contains an open reading frame consisting of 1,014 nucleotides corresponding to

The dtaAX gene encoding a pyridoxal 5'-phosphate (pyridoxal-P)-dependent low-specificity D-threonine aldolase was cloned from the chromosomal DNA of Alcaligenes xylosoxidans IFO 12669. It contains an open reading frame consisting of 1,134 nucleotides corresponding to 377 amino acid residues. The predicted
