Abstrakt: The multifunctional enzyme enniatin synthetase was immobilized by adsorption to propyl agarose. The immobilized multienzyme retained 45% of the activity of the free enzyme; an operational half-life of about 15 h was estimated. Selective synthesis of several different enniatin homologues was achieved with propyl agarose-bound enniatin synthetase. In addition to enniatin A, B, and C formation, a selective synthesis of non-naturally occurring depsipeptides, containing norvaline, norleucine, or α-aminobutyric acid as sole amino acid moieties, was observed.
