The GreenLDH® enzyme assay kit consists of engineered leucine dehydrogenase and demonstrates activity exceeding 99% against the designated substrates

Several variants have undergone pilot-scale testing, exhibiting greater than 90% activity with 99% e.e. at substrate concentrations of 100-120 g/L, temperatures exceeding 40 °C, pH values exceeding 9.0 and ammonium formate 10 g/L
