The invention relates to a method for preparing alpha-ketopimelic acid, comprising converting alpha-ketoglutaric acid into alpha-ketoadipic acid and converting alpha-ketoadipic acid into alpha-ketopimelic acid, wherein at least one of these conversions is carried out using a heterologous biocatalyst. The invention further relates to a heterologous cell, comprising one or more heterologous nucleic acid sequences encoding one or more heterologous enzymes capable of catalysing at least one reaction step in the preparation of alpha-ketopimelic acid from alpha-ketoglutaric acid.
