Application

Application Comment Organism
synthesis development of a bienzymatic biocatalyst system comprising an N-succinylamino acid racemase from Geobacillus kaustophilus CECT4264 and the enantiospecific L-N-carbamoylase from Geobacillus stearothermophilus CECT43. The biocatalyst system is able to produce optically pure natural and non-natural L-amino acids starting from racemic mixtures of N-acetyl-, N-formyl- and N-carbamoyl-amino acids by dynamic kinetic resolution. The fastest conversion rate is found with N-formyl-aminoacids, followed by N-carbamoyl- and N-acetyl-amino acids, and the an N-succinylamino acid racemase proves to be the limiting step of the system due to its lower specific activity, overview Geobacillus stearothermophilus
