An enzyme (AspRedAm) capable of coupling carbonyls with a variety of amines in a reductive amination has now been discovered. Kinetic studies revealed that the enzyme catalysed both the imine formation step, as well as the reduction step. Structure and mutagenesis studies have highlighted essential catalytic residues and preparative scale examples have demonstrated total turnover numbers of up to 32,000.
