The biosynthesis of dopamine (DA) from L‐tyrosine as starting material is an excellent yet challenging strategy. Here we developed a versatile, multi‐enzymatic platform for the biocatalytic preparation of DA in a continuous mode with excellent conversion (90 %) and reaction time (45 min). The system exploits the immobilization of a decarboxylase from Bacillus pumilis (Fdc) and a tyrosinase from Agaricus bisporus (Tyr), which were combined to mimic the in‐vivo synthesis of DA (both primary and secondary metabolisms) giving rise to an efficient strategy with a considerable reduction of process associated costs and environmental impact. To enhance the system automation, an in‐line purification via catch‐and‐release procedure was added.
